Waymo’s fleet of driverless vehicles are operating in more cities and a study indicates that may reduce crashes on roadways. The study, a non-paid partnership between Waymo itself and reinsurer Swiss Re, indicated Waymo’s cars result in fewer insurance claims than those operated by people.
Swiss Re analyzed liability claims from collisions covering 25.3 million miles driven by Waymo’s autonomous cars. The study also compared Waymo’s liability claims to human driver baselines based on data from over 500,000 claims and over 200 billion driving miles. The results found that Waymo Driver “demonstrated better safety performance when compared to human-driver vehicles.”.
The study found cars operated by Alphabet’s Waymo Driver resulted in 88 percent fewer property damage claims and 92 percent fewer bodily injury claims.
Swiss Re also invented a new metric to compare Waymo Driver against only newer vehicles with advanced safety tech, like driver assistance, automated emergency braking and blind spot warning systems, instead of against the whole corpus of those 200 billion driving miles. In this comparison, Waymo still came out ahead with an 86 percent reduction in property damage claims and a 90 percent reduction on bodily damage claims.
Of course, there are two glaring issues. First is that Waymo currently only operates in cities, which, yes, account for the bulk of crashes in the US, but rural areas account for a much higher number of crashes (especially fatal ones) proportional to their population. (The study, incidentally, states that having exurban data included in the baseline metrics actually cuts against Waymo’s true safety numbers.) Second: Waymo simply hasn’t been around that long. It’s very hard to get an accurate measure of the system when its real-world testing period has been so relatively short.
The numbers may look good for Waymo Driver in studies but they aren’t perfect by any stretch. Waymo issued its second recall over the summer when one of its robotaxis hit a street level telephone pole at 8 mph in Phoenix. The National Highway Traffic Safety Administration launched an investigation into Waymo and found 24 incidents that involved crashes or traffic violations.
