Hier een stukje van de Reason Foundation:
- The report comes from RethinkX and is called “Rethinking Transportation 2020-2030,” released in May 2017. Its headline claims include the following:
* Fully autonomous vehicles (presumably SAE Level 5) will achieve regulatory approval and be on the market in 2020.
* By 2030, those AVs will provide 95% of all [surface] passenger miles of travel.
* Those 95% will all be in shared vehicles (Mobility as a Service), rather than in personally owned AVs.
* These AVs will all be electric, and will last 500,000 to 700,000 miles on their initial battery pack.
These assumptions are shared by virtually no one actually working on AVs, whether at technology companies or traditional auto companies. The past year has seen a growing number of articles explaining that full autonomy (on all kinds of roads, in all kinds of weather, etc.) is turning out to be a much harder problem than many researchers expected. Most expect gradual introduction of AV features in the next decade, with full Level 5 not being likely until at least 2035 or beyond.
A far more realistic assessment of future mobility was released in May 2018 by S&P Global Ratings, “The Road Ahead for Autonomous Vehicles.” S&P’s analysts conclude that “mass adoption of driverless autonomous vehicles (AVs) [is] still decades away.” By contrast, they expect a faster penetration rate of electric vehicles (EVs), especially if there continue to be government “incentives” (subsidies) for those purchasing them. (S&P’s EV projections are somewhat exaggerated by including plug-in hybrids.)
S&P developed three scenarios (low/medium/high) for AV penetration, depending on a array of assumptions about technology, the price premium over conventional cars, extent of government “incentives,” growth in ride-sharing/ride-hailing (Mobility as a Service), etc. For the 2020 to 2030 period, the fraction of AVs in the total light-vehicle fleet by 2030 is projected at <1% in the low scenario, <5% in medium, and <10% in high. In Phase 2 (2030-2040), the AV fraction of the vehicle fleet would be <5% in low, <15% in medium, and <35% in high.
I find the assumptions underlying the three scenarios to be reasonable, and a number of implications for highways and travel emerge. First, even in the high (“disruptive”) scenario, only 35% of the light vehicle fleet will be AVs by 2040. So that means our roadways and highways are going to have to deal with a mixed fleet for many decades. That is far different from popular media visions of a near-term all-AV future. Second, S&P suggests that the early impacts of Level 5 AVs will be felt most by transit agencies and parking enterprises. Between 2020 and 2030, S&P expects an increase in urban traffic congestion, due partly to the continued growth of ride-hailing.
