Is it just me or the majority of people on driving uk are just imbeciles or are they just sarcastic?

I swear people on there don't know whether to take a shit or wind their watch. I can't help but laugh at people on there.

•Or you just click on the comments and everyone is hurling abuse at each other "or you waste of air or you are an entitled prick"

•Driving a bit over limit bad but driving way under 20 in a 70 is apparently acceptable.

•(genuine question I saw yesterday) "A cop pulled someone over and I was driving past doing 3 over the limit what are the chances I've been caught or am I being paranoid"

• or questions like "there was a speed van on a bridge and I was doing 90 in a 40 I already have 3 points how many more will I receive"

(I know it's unrelated to this forum but everyone on their just can't help, but blow my mind)
