Why are people more willing to burn cars now?
Just vandalism? Boredom?
I think there's more to it than that. The traffic in Oxford and London is getting unbearable, and according to a recent study the pollution in Oxford is so bad that standing on a street corner in the city centre is the equivalent of smoking three packets of fags:
People who are willing to lash out at the daily assault are more likely to lash out at something that's hurt them first.
I say good on them. The damage done to the atmosphere by a few burning cars can be offset long-term by fewer cars being bought, and public transport use going up.
I got rid of my car, and life's more difficult for me now in some ways: it meant changing jobs, and changing a lot of how I live my life. But at least I'm not attacking anyone now with toxic gas.
If someone drives a car and doesn't really need to, they're assaulting you and the people you love, and both have a right to self-defense.
