My teenage son recently got his first electric wheelchair. He drives too fast, he puts holes in the hallway wall and takes way too many chances with his and others' safety!
I've been worried and asked him to slow down and be careful. He won't. So, I decided to stop worrying about my son's driving and take advantage of it. I got one of those bumper stickers that say, "How's my driving?" and put an 0800 and number on it.
At 20 pence a call, I've been making about £25 a month!
