"J. Clarke" wrote in message ... The person on the scooter is in a much more unstable position than a person walking or standing. OTOH the crafty buggers probably feel the resistance and abandon within a shake of a lamb's tail. The scooter's 2 up and gyrostabilized--you've got anywhere from 400-1000 pounds of mass going for you depending on the value of "scooter". Sure it is, but the passenger grabbing the bag is not attached to the scooter except by a small amount of friction of his bum on vinyl seat and feet on small rubber pegs. Do go down to your neighborhood Suzuki dealer and examine a Burgman. The grabber is attached to the scooter by feet on floorboards, not pegs, a backrest, and an arm around the driver, who is similarly attached and also has both hands on the bars. Sorry, I didn't realise they all rode Burgmans. They don't, but many other scooters have similar features. And many don't. Don't assume that "scooter" means "50 year old Vespa". Nor one with a backrest. In any case you're clearly arguing for the sake of argument. Just like you are. Any argument can be defined that way if you want I guess. Trevor. |

But the 50 year old ones that whatsisface seem to be equating with "scooter" are. Fact is many times they are NOT scooters at all, they are often small, or even large motorbikes. YOU are the one making stupid assumptions, like all scooters in the last 50 years have backrests, when they are a VERY SMALL minority. Trevor. |

In Asia the people doing the grabbing generally mass about 50 - 60 Kg. The scooter can keep on going but he's not going with it. And as I said, as soon as the strap doesn't cut and there is resistance he's just going to let that one go.

And as I said, as soon as the strap doesn't cut and there is resistance he's just going to let that one go. (A pound is not "mass"). The SI unit is the kg. It describes mass, which is both affected by gravity and has inertia. In this case, inertia is what is important. Say the grab happens at 20 km/h speed differential (you walk briskly at 5 km/s, the scooter is passing you at 25 km/s from behind), the grabber is not holding on the vehicle or driver at all, you're 100kg and the grabber is 50 kg. What happens --- best case for you --- is that you're suddenly accellerated to 12 km/h and the grabber braked to that speed. I.e. half your body weight has suddenly slammed into your upper body from behind, at roughly the speed you'd be able to sprint (i.e. 100 meters in 14 seconds). Since you have no chance to react --- you're not even seeing the grab coming from behind --- you'll be slammed over, your camera smashed on the ground and your face kissing the concrete at high speed. Now imagine what happens if the grabber is seated well, braced against the impact and holding onto the driver (which again holds onto the scooter. Guess the effective weight of the grabber is 3 times his 50 kg. You'll be kissing the asphalt much faster than Usain Bolt could run into a brick wall if he wanted to. You might pull the grabber off the scooter, but you're going to hospital and your camera will be dead from the impact anyways. More likely, the grabber will let go as you are yanked forward and plant your face on the sidewalk and slam your camera down with you. -Wolfgang |

Trevor, the discussion was of a certain class of crime, not of the scooter market. The fact that you feel that it is essential to divert the discussion into one of the details of scooters says that you are an annoying twit who can't stand it if you are not the center of attention. I only responded to the twit who brought it up. That you think I am not even allowed to respond proves more about your stupidity than any desire for attention on my part. Trevor. |

Sorry, but you are not only being pedantic, but now you are being stupidly pedantic. |
