If you are going slower you can make up for missing details, missing a brake signal, missing a pedestrian. Speed is the underlying reason accidents happen. No

If you are going slower you can make up for missing details, missing a brake signal, missing a pedestrian. Speed is the underlying reason accidents happen. No one is creeping at 2 MPH and just running into things, they have time to stop. This doesn't even take into consideration that speed results in significantly larger impact (and thus damage to passengers, environment, and vehicles)
