Thats BS, when you are driving you should be sitting up straight and close to the wheel (the wheel should be resting at your wrist with your arms straight) so if you have an accident your elbows dont lock thus destroying your arms.
If you dont believe me then go have a sit in a Group A car, or if you want more reasons give Aarron McGill a call and do some driver training.
What is dangerous is people who have the seat back all the way, they cant operate the car correctly and if they have an accident they will either slide down under the wheel or get caught in the belt.
As for your claims to ban greek women, taxi drivers, etc etc. I think that is a unfair generalisation, what we should do is give people more driver training, and make professional drivers resit there driver training exams on a regular basis.
