Toss me an explanation

There is a new commercial for Suzuki advertising that their cars have the #1 warranty. It features people driving around in Suzuki cars and throwing a set of keys to each other. There are several things that confuse me about this: first, the people are already driving around, what do they need keys for? The people playing are actually all passengers, so maybe they need keys so they don’t have to bum rides from whoever is driving, but still, they clearly aren’t hurting for transportation. Secondly, what does any of this have to do with the warranties? Nonsense is irritating.
