I'll add on that speeding is the biggest contributing factor in accidents. And accident outcomes get exponentially worse above 30mph. For every 10 mph of increased speed, the risk of dying in a crash doubles.

There's a great paper which I can't find any more that said "going faster makes you take longer to get to the destination"; they showed the expected value for arrival time was longer at speed due to higher accident rates.
