I was quite lucky with my dad. He was moaning (as usual) about the price of fuel & car insurance & we talked about why he kept a car when he only used it for local shopping.
I talked him into buying an electric scooter - 8mph, about 35miles range, zero tax & insurance & almost zero running costs - plus he could get it even closer to shops than his blue badge allowed - result
A mate of mine went about it a different way - he kept 'tinkering' with the car without his dad knowing - every time his dad tried to use the car it had a new fault preventing it from starting. Of course, he just happened to know a really great mechanic (
) who'd nip round & perform miracle surgery (mate's rates - loads of coffee & choc hobnobs :yum
(course, it's so easy to fix when you know what the problem was. The hard part was making up 'faults'.
The old boy finally had enough of the messing about, sold the car & bought an electric scooter.
