Speed limits in a school zone should be 15 mph, but we care more that the children are safe than some number. If we have robots that are able to react inhumanly fast and are proven to be able to stop and not run people over, then they should be able to go at whatever speed that has them not running people over.
A law that sets the legal maximum speed as also the legal "must not meet or fall below" speed.
I dunno, seems problematic.
the speed differences you are referring to are road design situations such as highways dumping traffic into downtown traffic. delta V isn't recognized as a severe problem by IIHS nor DOT. speeding very much is.

--What is the effect of speed differences? In addition to absolute speeds, the speed differences between vehicles also have an effect on the crash rate. This effect is studied in two ways. The first type of studies are those that compare the crash rates between roads that have a large speed variance (large differences in vehicle speeds during a 24 hour period) and roads that have a small speed variance. These studies mostly conclude that roads with a large speed variance are less safe (Aarts & Van Schagen, 2006). The second type of studies are those that concentrate on the speed differences between the individual vehicles that were involved in a crash and all the other vehicles. The first studies of this type were conducted in the United States in the 1950s and 1960s, e.g. Solomon (1964). These studies always found a U-curve: the slower or faster a car drives compared with most of the vehicles on that road, the more the risk of being involved in a crash increased. However, more recent studies, especially those carried out in Australia (e.g. Kloeden et al., 1997; 2001; 2002) that used more modern measuring instruments and used a more accurate research design, reached a different conclusion. They still indicate that vehicles that drive faster than average on that road have a higher crash rate; vehicles that drive slower, however, were found not to have an increased risk (Figure 3)
Slower is safer!
I know, I’m asking if they adjust for how humans actually drive. There are places in America (funny enough, Phoenix and LA) where going 25 in a 25 will subject you to aggressive driving from others.
1.4 times as fast is not "almost" twice as fast. 50 is twice as fast as 25; 49 is 1.4 times as fast as 35 which is 1.4 times as fast as 25.
Wait, you are asserting that speed limits are set expecting that everyone will obey them?
Can't we just pass some laws that require Waymos to drive above the speed limit at all times, like normal drivers?
