I can simplify that. Fit every new car with a tracker from the factory. If you walk around with a mobile phone you've got one in your pocket anyway so the snooping argument is moot. Your mobile provider has access to that information so the case against letting insurance companies have it too is also irrelevant. If you want to be off the grid then wear sheepskins and live in a cave. If you want to protect your £££££ vehicle then let it be tracked. Many vehicles already have this technology but at the moment we ask it to find the nearest supermarket.
If anyone wants me to look at Arab/Israeli two state solution or what we should do about the glaciers melting just give me a shout.
I also find contributions from people who watch too much telly amusing too. The sort of physical violence you may experience in real life isn't reflected in TV drama. It's nasty, vicious and it hurts. And trust me, you're allowed to try and defend yourself regardless of what The Daily Mail may tell you. Battering someone unconscious because they try to steal your car is a different matter entirely.
