I always assume that people are lazy and try and click the least amount of squares as possible to get broadly the correct answer. Therefore, if it says motorbikes just click on the body of the bike and leave out rider and tiles with hardly any bike in them.

If it says traffic lights just click on the ones you can see lit and not the posts and ignore them if they are too far in the distance. Seems to work for me.
