Not DMV specific, but perhaps you’ve experienced vehicle associated danger as a cyclist…
Some potential comments:
Regulate vehicle weight/hood height;
Require systems to detect/brake for people;
Require systems to control speed;
Include women and children crash test dummies;
Rate vehicles on safety for people;
Horn volume should be as loud for the driver as it is for the people right outside the vehicle (i.e. if a driver is ticked about traffic not moving, maybe their eardrums should be vibrating as much as those of the innocent people who aren’t in metal boxes).
