We've all been there, and I'm pretty sure we've all had our fingers burned as newbie drivers. (Hit a spanking new 206 in a car park the day I got my first car
)
I think the problem stems from inexperience. It's all very well being able to drive with an instructor sat next to you, but as soon as you're in the car on your own, that's when you really start learning to drive, and maybe bump wing mirrors or have car park dings and i don't think there is anything really that can be done about that.
When people act stupid and try to drive beyond their abilities that's when things get nasty. Maybe there should be a system similar to motorbikes where you can only drive say up to a 1.2 for your first two years, then have it upped to a 1.4 until you have 5 years no claims, or something.
