Of course, it's slightly ironic that many drivers will react quite furiously to any hint of damage (or even a fingerprint) inflicted on their car, yet many of them drive in such a cavalier way that they practically invite a collision!
Yes, the behaviour of some drivers is quite funny and can be inconsistent. I used to be a little touchy about damage to my car, but age and other priorities have knocked those corners off me.
However, I think we should be careful how we word our sweeping generalisations. I know very many drivers, but few (if any) would react furiously to a fingerprint on their car. Few drive in such a cavalier way that the practically invite a collision.
Cyclists, on the other hand.... Don't get me started. Few would doubt for a moment that many of them are all the same! Of course, many cyclists are just the sort of people who would go around leaning on cars just to provoke a furious reaction from a driver - which is slightly beyond irony.
There! Every lazy generalisation causes an equal and opposite lazy generalisation, whether in the presence of irony or not.
All road users should be lovely to one another.
