Actually, several studies have shown that cars go through traffic lights far more than cyclists. The reason that this appears not to be so when you're driving is probably that you see cyclists going past and going through. If you're cycling, and you're sitting at the lights as I normally do, you see a tailgating series of cars whizzing through just after the lights turn red. The drivers further back in the queue don't see these - but they're far more dangerous than the cyclists who go through.

One study, which I can direct you to if you'd read it, found that all forms of transport are 'scofflaws', but cyclists less so than others; and when asked why they went through red lights, etc, when they did, drivers answered "to save time", but cyclists answered "it's safer".
