> - Never drive on unfamiliar roads > - Never drive on the freeway --- i.e. at high speed where reaction times are more limited. The paper says human benchmark being used is only from the zip codes Waymo operate in, so they are quite comparable. In fact, they have this bit about including freeway mileage in the human benchmark: > Waymo also almost exclusively operated on surface streets (non access-controlled freeways) with a unique distribution of driving that is representative of a ride-hailing fleet. In contrast, the benchmark represents the privately insured driver population that resides in these geographic regions. The associated benchmark mileage has more freeway driving than the Waymo ADS. There are several considerations when examining these results with respect to this limitation. First, freeway driving has a lower crash rate (Scanlon et al., 2024a). Including freeway driving makes this benchmark crash rate artificially lower, so, by including freeways in this study’s benchmark, the benchmark crash rate underestimates the true driving risk of where the Waymo ADS operates. Second, driving outside of these denser urban areas that the Waymo ADS operates would likely represent a reduction in overall relative crash risk. > - Never exceed the speed limit or follow too closely How is this a bad thing?
