Clearly said Cherry Picker is parked there a lot, hence the driver lives on said street.
Sounds like this is more a Neighbour Dispute about parking than anything else.
Well it’s not actually, it’s causing people to have to reverse down the street which is actually illegal I have tried asking said engineer to even turn the vehicle around to create more room or maybe park on their extremely large drive way but to which he just gives rude remarks, elderly people are having to park at the bottom of the hill and walk all the way up to their houses because of this
Call on the law if you think Mr Pig's behaviour is illegal. But you'd have to prove it and then go to the police as @gg30340 suggested, though getting them to act might be even more difficult than getting a hug from a GP.
