The driver of this car is a complete w****r. He is too thick to realise that you do not lock dogs in cars in hot weather. He must be. Or he doesnt care in which case he shouldnt have any pets. People like this make my blood boil. What a thick uneducated twat.
Was the vehicle parked or waiting to give way to oncoming traffic on account of the parked vehicle in front of them?
If they waiting to give way then they have priority and should not be over-taken..same would apply in reverse. If they are parked, they didn't check their mirrors properly or signal before pulling out.
Whatever their response, their actions speak volumes regarding their inability to drive to a suitable standard together with their obvious desire to use a vehicle to threaten a vulnerable road user and force them into oncoming traffic. Please report this person to the police as soon as possible.
Various police forces have different way to report these types of driving skills. Im manchester its:
