Re: I said, "Get your CAR OUT of the BIKE LANE!"
When I were a lad we could buy 'mini rockets' which came in a pack of 5 or 6 and included a slow match sort of thing.
Place mini-rocket in end of handlebars (no kids bike has end stoppers), ride bike, fire rockets sideways.
Never got round to mounted Roman Candle or 'air bomb' battles', no idea why not.
(Not that I'd recommend any such foolish and dangerous things these days, oh, no.)
