How's my driving?

I would (if I had the money, time, motivation and ability) set up a website called how's my driving. This website would allow anyone to post comments about the driving of a particular registration number. Each post would require the poster to note the time, date and what the driver did wrong.

Whilst this site is likely to upset some people who repeatedly get negative comments about their driving, it would provide a non-violent outlet for road-rage and might even encourage people to improve their driving.

The site would be ad-funded with the most common clients including motoring organisations (AA or RAC) and car insurance.

The site would allow anonymous posting so people were not afraid of retaliation when making a post.
