Don't they see how anti-social it is? If I start my car very early/late in the day I have a little grimace to myself about whether I'm disturbing someone's sleep. I certainly don't rev the bullocks off it and squeal the tyres round the corner.
True, and I think this is the main point indeed. And in this case you are right! When I had a job that started at 7am, so had to leave for work by 6:40am, and my car was off the road at the time so had to use my (rather loud) motorbike to get to work on each day for a bit, I'd push the thing out the garage, then start freewheeling it down the road (lived up a slight hill at least) before I'd then start the ignition once I'd got a few hundred metres down the road and up to about 20mph or so to lessen the impact of the noise it made.
People derive pleasure from all sorts of different things, and it's not up to us to tell them how to spend their money. But it is up to everyone to be socially responsible. I for one like loud music, and it's not the kind of music that most people would enjoy! Therefore I tend to go out to clubs, or listen at home when nobody else is around, or in my car on the motorway when there's nobody else to annoy. When there's other people around that may not like it to annoy, I turn it off or down.
In this respect you do come across a lot of the modded shopping trolley hatchback brigade that think it's their god given right to make as much noise as possible, as much of the time as possible, and for that they should get their wrists slapped! Personally though, if I derived enjoyment from ragging my car around someone's housing estate at 12:30 at night, I'd want my car to be as quiet as possible, so there was less chance of people hearing me do it and so less chance of the cops turning up! But maybe I'm too old and wise now
