    Is there a "clutch"? When we learned to drag race, to be fast you had to twist the grip to the stop as soon as the lights dropped. We use the clutch to control wheelspin/wheelies. Easy on a slow bike, a little harder when we got more powerful bikes
    Most electrics have no transmission. They do not show the left handlebar so I don't know if there is some kind of clutch. My quess is it would be just an engage or disengage shifter and like the cars everything is throttle controlled. I don't see these even having regenerative braking unless it is being done by the motor at off throttle with input from the foot brake to the rear wheel.

The car reignited for hours after the crash, which is typical for battery fires. You just can't put them out. Sure, gasoline is plenty flammable, but Fisker, for example, basically went out of business because they couldn't keep their cars from catching fire.
    That is very sad. However, it's the first I've heard or tesla battery fires so I don't think they can be that common?

    There were a couple house fires/cars burning down during charging when the Model S first hit the market I seem to remember.

    However I think anything like that has more to do with questionable qc at Tesla then it being electric. I havent heard of any fires from say a Nissan Leaf.

    Musk talked about a swappable battery years ago but has never delivered upon it. This was primarily to solve the charging time issue (and battery life) but I could see it addressing the post-crash safety issues if they can separate the two(car and battery). Tesla uses lithium-ion batteries that are supposed to have some of the best construction for cell joining and electrical busses. Others have used both lead-acid and NiMH (Toyota has used both and has not had the same issues...they do not Lithium-ion). I think the other factor that may be at play here is the Tesla supercharger. Pushing charging too much can break things down to the point they explode. If you read the engineering analysis of the Model 3 they tore down you find there are many glaring mistakes in Teslas that would never happen at a seasoned auto company. The cars all have some glaring flaws in build quality. They did feel though the batteries were constructed very well, so this takes me back to the charging. Also when a friend took me for a ride in a dual motor S in the ludicrous mode they heat the batteries for a long period before(like 50 minutes) you can use it. This did not seem to make sense, but I've never really dealt with lithium-ion batteries. Most other electric vehicles concentrate on cooling the batteries. So there may be several things conspiring here.
    Yes, that was him.

    There’s something about the Tesla batteries that I believe make them more prone to exploding or catching fire. I don’t think I’d even get in one at this point.

    It’s happened several times that I’ve heard of.

    There are a few reported (close to 45 total). Just looking at our area this is the second that has caught fire over the period of a year in South Florida.

    The cars and bikes thread!

    Apparently also on this past Sunday a Model X ( the SUV model)up in Vermont that hit a rock while traversing a frozen lake to go ice fishing burned to the ground. Fortunately no one was in this one when it burned up.

    One can only drop one's jaw as to how much noxious pollution these battery fires cause.
