It's fucked up that it is scarier to be on the road in control of a vehicle that weighs less than the person/people it's transporting and rarely hits 30mph than it is to be on the road in control of a vehicle that weighs several tonnes and can do well over 100mph.
I am no traffic engineer, but I think we should simply design roads that make drivers nervous and scared so they slow the fuck down. We shouldn't want drivers to feel comfortable.
