Many years ago, I came up with a concept to fix these issues. My concept was as follows:
1) Cars, SUVs, and light trucks used for non-commercial purposes like commuting, short trips and "family car" duties" would remain mostly the same as they are now, with the following changes:
a) The driver's controls inside the car would be removed.
b) There would be a driver's seat bolted to the very front of the front bumper right in the middle, so the driver would be right at the front of the car.
c) The necessary driver controls would be attached via a lightweight framework around the driver's seat so the driver could properly operate the vehicle.
d) There would be a lightweight transparent bubble mounted around the driver's seat to protect the driver from wind and rain, with the appropriate windshield wiper to protect their view, and a door to allow them to get in and out of the driver's seat. Note: There will be NO "crush zone" or padding in the bubble: The driver will be unprotected by the bubble except for wind and precipitation.
Benefits:
1) No more tailgating. When the driver realizes that THEY are the crumple zone and they will be the very first to die in a rear-end collision they will instinctively back off.
2) No problems with visibility at all: The bubble will be completely clear so the driver can see everything in front and to the sides of the driver's seat.
3) More civility on the roads and much less danger to pedestrians, bicyclists and motorcyclists. If the car hits any of these people, the bubble will be weak enough so that the injuries to the driver will be commensurate with the injuries to the pedestrian. Also, the bubble will be designed so the drive will be eye-to-eye with any pedestrians, and any offended person will be able to walk up the the bubble, open the door and punch the driver in the face if they try to drive the car in a manner threatening to the person.
4) Driver awareness. The driver will be viscerally aware of the risks of operating a motor vehicle because they can see and imagine just what will happen to them in an accident. They will drive much more carefully because they will instinctively know that if they make a single bad mistake, they're dead.
5) Passenger protection. While the driver will be utterly unprotected by anything, all the passengers will continue to enjoy the protection of the airbags, crumple zones and padding in the passenger compartment. So they will be just fine in most crashes, while the driver may be less than a grease spot on the road.
As long as we continue to cater to drivers wanting to "feel safe" by putting them in bloated vehicles with poor visibility and lots of padding, they will not have enough motivation to drive more carefully because in their reptile brain, they are "safe". If you put them in a vehicle guaranteed to kill them if they get in an accident, then they will drive more carefully.
