I recently read that a 70mph accident is considered “unsurvivable.” Regrettably I don’t recall the source. Because people survive accidents that happen on 70mph speed limit highways all the time, I assume two things. 1. That the accident has to happen AT 70mph. And that 2, most people are able to slow down or perhaps the vehicle hits something first, glancing blow, that sort of thing, which brings the speed down, making it more survivable. So yeah, I think that makes 100mph suicide/murder.
