[Roadsters] A shoulder belt solution

If you have a roll bar, mount the shoulder strap to its support.  If you do
not, the wheel well  mounting is really too low to be safe (unless you are
4'  6"  tall). The compression generated by the strap is not good in a crash
and may cause spinal damage (collapsed vertebra).  Better to let it slip off
your shoulder and depend on the lap belt alone.
