You won't be done under Con and Use for motor car horn offence of being too strident as it is not fitted to the vehicle, BUT

Waving it about on the move could lead to being prosecuted for driving in a position not having proper control, or if the circustances common law offence of conduct likely to cause a breach of the peace.

I would suggest best place to play with your horn is in bed...

I take it that the original post is a windup.

Or a (failed) justification) for hooting at people.. many of whom will be innocent of any of the described "crimes".

Vigilante behaviour is not approved of in the UK. And hooting wildly at people - when there is no way of distinguishing at whom or why ... to me says more about the poster than anything else.. (if they are serious.. which I doubt)

EDIT

And I have a sense of humour except when people hoot wildly and loudly..making everyone sufer. Just plain vandalism.

I am well aware that nobody cares about my displeasure.

People throwing litter in front of my eyes - guilty.

People drinking lager before luncheon whilst walking down the street - guilty

People arrogantly and deliberately walking in front of cars making them slow down - guilty

Drivers who indicate when near the end of a manoeuvre, rather than before it starts (for example) - guilty

Parp parp!!!

ha ha very good.

My best one was a gang of ne'er-do-wells marching down a street in Toxteth, it was obviously their "turf". Gave 'em a good old blast and my, the abuse, the screams threatening vengeance! Obviously I made sure that there was plenty of clear road ahead. One wouldn't want to be caught at a red light, what?

Love it - the motorist strikes back. Just NIMBY please, I would probably have a heart attack!

Can you direct it at a couple of speed cameras for me please - just for the fun of it!

I think most people will just think you're a hooligan having a laugh.

The 'serious' message of your aerosol horn will be totally lost on anyone who sees or hears you using it.

Why not rig up a microphone in the car and PA speakers on the roof, then you can hurl amplified verbal abuse at the perpetrators of the misdemeanours that you come across while driving.
