Something has been itching at my mind for a few years..

Does anyone know whats up with the weird amount of dislikes you come across in media? It could be something super non-subjective that makes no statement about anything like a kitten playing with a toy and you see 100k likes with 2k dislikes.. Where do these 2k dislikes come from?

The latest video that made me wonder this is this:

Its a car that goes so fast it pretty much becomes an airplane. 67k people liked it but for some reason 800 people disliked it? Is there just bots that spam dislikes across youtube or is there some weird % of society that watches clips and hates them for no reason...
