Why Should Self-Driving Cars Look Like Cars?
Exploring the provocative question: what happens if autonomous vehicles break free from traditional car design?
As self-driving technology moves closer to everyday reality, a crucial question emerges: Why must autonomous vehicles (AVs) replicate the design and function of traditional cars? This article explores the history behind the car’s iconic design, challenges long-held assumptions about transportation, and discusses alternative visions for a society supported by autonomous mobility.
The Legacy of the Automobile: More Than Just a Vehicle
For over a century, the car has defined how cities are built, how people move, and how entire cultures express status and personal identity. The mass-produced automobile transformed not only transportation but also urban planning, economics, and lifestyle. The familiar shape, controls, and function of cars have become deeply embedded in our infrastructure and collective imagination.
- Infrastructure investment: Roads, highways, parking lots, gas stations, and repair shops were all developed around the conventional car shape and size.
- Symbol of status: For many, the car is not just a means of transportation, but reflects personal freedom, achievement, and identity.
- Civic structure: Neighborhoods, commercial centers, and suburbs were designed on the premise of private car ownership and use.
This past creates both an inertia and a challenge when considering any fundamental change, even as revolutionary technologies like self-driving cars become feasible.
Reimagining the Purpose of the Car
The self-driving car separates the function of travel from the act of driving. As the driver becomes a passenger, opportunities emerge to radically rethink vehicle interior layouts, safety protocols, and external design.
- Loss of the Driver’s Seat: When no active driver is required, seats can be rearranged for conversation, work, or relaxation, much like a train compartment or a mobile living room.
- No Need for the Traditional Dashboard: The familiar steering wheel, pedals, and instrumentation become obsolete, freeing up significant space and reducing manufacturing complexity.
Car interiors could be designed for sleeping, working, playing, or even communal interaction, completely reversing assumptions about what a personal vehicle should look like or do.
Why Do We Think Self-Driving Cars Must Imitate Current Vehicles?
Despite these new possibilities, early self-driving cars continue to mimic the look and function of traditional automobiles. This tendency stems from:
- Regulatory compatibility: Laws and standards currently require cars to meet established crash safety rules, even if the risk profile changes with autonomous driving.
- Public acceptance: Dramatic changes can foster fear and pushback; familiar shapes and controls help consumers trust new technologies.
- Economic pragmatism: Modifying existing vehicles with sensors and autonomous controls is faster and cheaper than developing new platforms from scratch.
- Transitional infrastructure: Roads, garages, gas stations, and insurance models currently serve conventional vehicles. A shift to dramatically different vehicles requires urban adaptation.

Manufacturers are hesitant to risk market penetration with radical new shapes until technology, regulation, and public expectation catch up.
Imagining the Post-Car-Shaped Autonomous Vehicle
What if autonomous vehicles did not have to look or function like cars at all? Technological advancements allow us to imagine vehicles that adapt to diverse, specialized tasks, or evolve entirely new forms suited to novel urban landscapes.
Potential Directions for Autonomous Vehicle Design
- Micro-mobility Pods: Compact, slow-moving vehicles designed for single passengers or small groups, tailored for urban cores where speed and range are less important.
- Modular Transport: Adaptable units that combine or disconnect for various functions—family outings, cargo delivery, or mobile meeting rooms—replacing one-size-fits-all car models.
- Flexible Interiors: Swiveling seats, transforming tables, beds, and entertainment centers, all possible by removing the conventional driver orientation.
- Purpose-Driven Exterior Designs: Streamlined delivery bots, event shuttles, and mobile retail units molded for efficiency, safety, or branding, not just aerodynamic performance.
- Eco-Friendly Construction: Lightweight, recyclable materials and efficient shapes, unconstrained by the dictates of “driver” safety.
The Social Contract: Ethics, Street Design, and AV Integration
The advent of autonomous vehicles is not just a technical issue—it triggers debates on urban planning, social contracts, and the basic rights of road users. Some of the most pressing questions center on how AVs will reshape urban environments and human behavior.
The Jaywalking Problem and Robotaxi Exploitation
Pioneering studies and urban experiments highlight the so-called “robotaxi exploitation” phenomenon, where people quickly learn that AVs will always yield, prompting many to recklessly cross streets or ignore traffic signals. This dynamic leads to several profound issues:
- Ease of pedestrian exploitation: The inherent safety programming of AVs (always braking for people) can encourage pedestrians and cyclists to take more liberties, potentially gridlocking urban streets.
- Changing risk calculation: The classic balance of power between drivers and vulnerable road users (based on mutual risk) breaks down when one side (AVs) is always programmed to minimize harm, enabling new forms of disruption.
Four Possible Paths for Addressing Robotaxi Exploitation
| Path | Description | Implications |
|---|---|---|
| Acceptance | Let pedestrians and cyclists take advantage—accept new behavior as inevitable. | Potential traffic paralysis, slow mobility for everyone; growing norm of disruptive behavior. |
| Authority | Increase enforcement or penalties (e.g., fines for jaywalking). | Resentment, civil liberty debates; policing challenges; possible equity issues. |
| Separation | Physically separate AVs from other street users with barriers, exclusive lanes, or grade-separated roads. | Redesigns cities, potentially restricting pedestrian and cyclist freedoms; large urban infrastructure costs. |
| Culture | Shift expectations via social campaigns or education so people cooperate with AVs. | Slow, difficult to engineer; risks ignoring underlying power imbalances in the street. |
Past and Present: Where Do We Go from Here?
History provides a warning. The rise of the car a century ago led to laws, physical barriers, and social norms restricting pedestrian access to streets once freely used by all. Grade separation (pedestrian overpasses, fenced crossings) has already been proposed for AVs to avoid gridlock. However, these solutions threaten to repeat the mistakes of the past—remaking cities for technology rather than for people.
Rethinking Urban Space for People, Not Just Cars
If we simply fit self-driving technology into yesterday’s car-shaped box, cities risk doubling down on designs that already strain the environment, social equity, and quality of life. AVs offer a rare chance to reimagine:
- Public space allocation: Streets and intersections redesigned to prioritize pedestrians, cyclists, and community life, rather than channeling everything toward faster vehicles.
- Urban density: With less need for parking, more land may revert to housing, parks, or commerce.
- Safety and sustainability: Lower speeds and smarter design can reduce collision risk, noise, and pollution.
Urban planners and residents alike face a fundamental choice: retrofit cities to accommodate new forms of robotic traffic, or seize this moment to center people in urban design and encourage diverse, creative transportation solutions.
Design Freedom: The Untapped Creative Potential of AVs
By detaching from the classic automobile form, designers and manufacturers could embrace:
- New aesthetics: Vehicles shaped by function, safety, or brand identity, not by legacy expectations.
- Accessibility for all: Custom-built AVs for children, seniors, or those with disabilities, without awkward retrofits.
- Contextual adaptation: Vehicles sized and styled for neighborhood streets, dense urban cores, or sprawling campuses.
Autonomous vehicles could look like anything the imagination allows: moving couches, transparent bubbles, delivery droids, or even walk-on, walk-off trams that glide at pedestrian speed through plazas.
Challenges and Risks: What Stands in the Way?
Despite the clear upside, several obstacles impede the radical redesign of AVs:
- Safety standards: Regulations demand strict crashworthiness even when collision risk drops in low-speed, pedestrian-dominated environments.
- Perception and habit: Many users equate traditional car design with safety, control, and reliability; unfamiliar shapes may alienate or intimidate.
- Technical hurdles: Advanced sensing and decision software must mature to safely accommodate radically different body styles and user interfaces.
- Economic inertia: Major manufacturers invest billions in conventional platforms; pivoting is costly and uncertain.
Nevertheless, the greatest risk is missing the moment to establish a new paradigm for transportation and urban design.
Frequently Asked Questions (FAQs)
Q: Could radically designed self-driving vehicles help cities reclaim public space from cars?

Q: Will most people accept autonomous vehicles that don’t look like conventional cars?
A: Acceptance will grow gradually as users experience the safety, comfort, and utility of such vehicles, but trust and regulatory support are essential for mainstream adoption.
Q: Could autonomous vehicles lead to increased street segregation through barriers or exclusive lanes?
A: If old patterns are repeated, yes. There’s real risk of cities adopting physical separation or restricting non-automotive mobility in the name of efficiency, potentially reducing urban freedom and vibrancy.
Q: Are there technical limits to how creative autonomous vehicle design can be?
A: Currently, technology, legal safety requirements, and cost considerations put constraints on extreme designs. But as systems evolve, new shapes and sizes will become practical and safe.
Q: Why might cities want to support radically different AV designs?
A: Doing so may foster inclusive, efficient, and sustainable mobility while reducing the dominance of traditional cars in public life.
Conclusion: The Shape of the Future is Up for Grabs
As technology disrupts the link between cars and driving, we are being offered a once-in-a-century opportunity to rethink not just vehicles, but cities, streets, and community itself. The true question is not just, ‘Why should self-driving cars look like cars?’ but also, ‘What do we want our world to look like in a future shaped by automation and mobility?’
