There is a great invention that you can buy in the US but is illegal to use in the UK.
It blocks all mobile phone signals within a 10 feet radius once switched on. If all car manufacturers fitted them as standard big brother would be happy, it can even be configured to only allow emergency calls so wouldn't cause an issue should an RTA occur.

They are illegal in the UK because you can't restrict network coverage, however probably a good idea to reduce the risk of mobile phone related accidents.
