100% agree with everything you write Nigel.i used to ride bikes till i got a few kids. when i got a car, i found it extremely easy to drive,you hardly have to think at all ! and you can make lots of minor mistakes that you wouldn't walk away from if you were on a bike
but biking taught me that it's the unexpected that will kill you , and i make a point of having as few distractions as possible while driving ,no radio,little conversation, and certainly no phone - especially when i see how many morons use them while driving a ton or more of metal that could crush me easily !
Talking of morons, my next door neighbours must have one of the worst cases of muchus useus phonus as no matter what time of day they always have their bloody enormous, latest spec i-phones stuck to their bloody ears, it's no wonder that both of their cars have so many dents and scratches!!
