lemat223 - Congratulations on being wrong so many times in one post.
It is the United Kingdom not 'England'.
It is not illegal to sell individual kitchen knives in the UK.
It is not illegal to eat and drive in the UK.
The UK has a Conservative government - it is not a 'socialist crap hole'. It has not had a Socialist government since the early '80s. You need a better source of foreign news (or you could just ask).
Driving is by a long way the most dangerous thing most of us do regularly. Anything that distracts the driver increases the risk. Controlled experiments show that, for reasons deeply rooted in human psychology, talking on the phone massively increases driving risk. It's entirely reasonable that governments legislate to reduce the number of unnecessary road deaths.
In the UK there is an offence of 'not being in proper control of a motor vehicle' that police have the discretion to use if a driver is distracted by anything that significantly affects his driving - food/shaving/makeup/books/sat nav/pretty girls etc. The mobile phone ban is a special case of this pre-existing law.
