The real danger on the roads is automotive, regardless of the fact that most drivers are safe an courteous folks.

Many active transportation folks eschew all aspects of car culture. I do. However, it could prove important to be able to identify details about a vehicle that was used as a weapon, for example in a hit-and-run.

All too often the police seem to be willing to do a poor investigation when cars are involved. Not being able to accurately identify vehicles only aids the police to this end. It's not right that this happens, so people in the general public should be able to make more positive identifications. For example, where an automobilophile might be able to make a split-second identification like '97 slate grey Taurus,' someone who didn't know much about cars might only come up with 'dark grey or blue sedan.' It wouldn't carry as much weight.

It's not the most pressing concern in the world, but it's a skill that could prove useful.
