The horrible alternative is to have to use Radio 2 and be forced to listen to people like Chris Evans, Ken Bruce and Jeremy Vine for the traffic reports. I'm afraid I don't find live traffic updates on the satnav in SE England any good. They simply take you from one jam to another to another and maybe an hour later dump you back on the M25 3 miles from where they took you off. Probably the best answer is the interactive smartphone app Waze, but it's a bit data hungry so you need an unlimited data contract.
