It'd make little difference. It's not likely to be worth much. Indeed, there are people willing to effectively have a disposable car to get free parking in London [and the fines + charges and so on, quickly surpass the value of far more expensive cars than the MOT failures you're hoping to crush]
These days I see adverts for "free scrap car removal" - which suggests you'd actually be offering a service. You might find my old car has a fridge in it too, could you crush that as well because the last one was a pain to get rid of? :)
At the end of the day, you can't stop rock'n'roll, no matter what spiteful measures you dream up to lose those feelings of low self esteem.
Crushing a car only matters in your materialistic, faithful-consumer mind.
Look at NI, they kneecap people, tar and feather them, beat them up and so on. The kind of wet dream a few here are having, but it doesn't work, it doesn't stop crime. If anything the opposite is true.
Of course, not doing anything doesn't work either. The middle ground is where it's at.
Think of it like tax, if you tax 100%, you'd get nothing in tax as people wouldn't bother working, whereas if you tax at 0% you get nothing by definition. The balance is finding the point at which you get the most money. But you see that this doesn't always equate to raising taxes.
Similarly, being completely oppressive just makes nothing against the law, what you'd basically end up with is riots or at worst civil war and your head on a stick. It's no different to anarchy where you'd have no laws. The balance is finding the point where you have minimum crime.
