It’s not uncommon for a motorists to see someone getting a little too close while your driving along and there’s nothing wrong with creating a motorcycle that can spit 15 foot flames in to the air, from the back of the bike, at the car behind them; it’s perfectly innocent.
I don’t see this as an anti-tailgating device, but rather a pyrotechnic device that’s their for show and nothing more.
Cars can shoot flames out the back of the car, from the tail pipes and the hood of the car; why shouldn’t scooters [or motorcycles]. I think its cool, and if you just happen to be behind me when it goes off- it’s just coincidence. Enjoy the show.
And if you should happen to take a lesson from the show, perhaps next time you won’t follow so close.
