Shared autonomous vehicles (AVs) are no longer a futuristic dream, they are here and operating in cities like Beijing, Oslo, Phoenix, and San Francisco. With advancements in Level 4 autonomy, these vehicles can handle most driving functions without human intervention, paving the way for a transformative shift in urban transportation. Yet, as McKinsey highlights in their recent report, the journey to widespread adoption requires a delicate balancing act across affordability, safety, accessibility, and sustainability.

Affordability and Profitability: Striking a Delicate Balance

For shared AVs to thrive, they must be more cost-effective or convenient than existing urban transport options while generating sufficient revenue for businesses along the value chain. McKinsey estimates that current costs of operating shared AVs are approximately $8.20 per vehicle mile travelled (VMT). However, with technological improvements, these costs could plummet to $1.30 by 2035, unlocking significant economic potential.

The primary drivers of this cost reduction include:

1. Enhanced Vehicle Utilisation: Greater adoption, optimised dispatching, and wider operating areas will boost the efficiency of shared AVs.

2. Advances in AV Technology: Simplified hardware, more efficient algorithms, and purpose-built vehicles designed for durability will cut costs substantially.

3. Economies of Scale: Larger fleets and centralised operations will lower costs, both at local and global levels.

While these changes promise affordability for consumers, operators must ensure sufficient profit margins, especially in competitive urban environments.

Safety: Winning Public Trust

Despite technological progress, safety remains a significant barrier to adoption. In McKinsey’s 2024 consumer survey, 53% of respondents cited safety concerns as the primary obstacle to embracing AVs. The media’s focus on accidents involving AVs has only heightened public scepticism.

To address these issues, companies are not only refining their technologies but also introducing dedicated safety frameworks and partnerships with regulators. Transparent reporting mechanisms and public education campaigns will be crucial in building trust. By highlighting the social, economic, and environmental benefits of AVs, operators can mitigate consumer fears and accelerate adoption.

Accessibility: Driving Inclusivity

Shared AVs have the potential to transform mobility for underserved communities, older adults, and people with disabilities. By integrating barrier-free vehicle designs and partnering with advocacy groups, operators can ensure these populations have access to reliable and affordable transportation.

Moreover, AVs can extend services to areas traditionally neglected by human-driven rideshare platforms. Incremental route expansions, made more cost-effective by the absence of human drivers, can foster inclusivity and mobility equity.

Sustainability: Reducing Emissions, Tackling Challenges

Autonomous fleets are primarily composed of battery electric vehicles (BEVs), which produce significantly fewer emissions than traditional vehicles. McKinsey’s analysis suggests that lifecycle emissions of shared BEVs could drop by 71% with advancements in design, operations, and supply chain sustainability.

However, increased adoption of AVs may lead to unintended consequences like road congestion and excess miles without passengers. To maximise sustainability benefits, regulators and industry stakeholders must address these challenges through smarter fleet management and urban planning.

The Path to Mainstream Adoption

While shared AVs are operational in select cities, their path to widespread adoption will require coordinated efforts across multiple dimensions. Beyond technological improvements, success will hinge on ensuring these vehicles are affordable, profitable, and safe while meeting the needs of diverse populations.

As McKinsey emphasizes, shared AVs could become a cornerstone of urban mobility, offering significant environmental and social benefits. Yet achieving this vision will require collaboration among automakers, policymakers, and technology providers. With these efforts, shared AVs can move from a niche innovation to a mainstream solution for urban transportation challenges.

This blog is based on the insights shared in McKinsey’s January 2025 report, getting on Board with Shared Autonomous Mobility. The full report offers a comprehensive analysis of the trends and strategies shaping the future of shared AVs.
