Most people here now travel by jetpack. I have even seen a couple flying hand in hand. They keep it on even when shopping!

[snip snip snip] Tonite's news report on tellie said the person plugged the wrong charger into the e-bike/e-scooter. (and parked it near the doorway, so the fire blocked them from safe normal exit!) I guess people have more than one "micro mobility device" and get confused about chargers. But I'm a bit surprised that these products use the exact same DC connector (but only a bit surprised). the other theory is that some folks are buying refurbished battery packs, and we don't know the quality of that refurbishment.

I always liked the handling of Volvos. They were very well balanced. I could take a highway entrance ramp at increasing speed, right up to the point where all four wheels would start to drift. I've never had a car that did that. It was always the rear for rear wheel drive cars, or the front for front drive cars. The one extreme example of that was the a Corvair I owned for less than a year. It died like most Corvairs, going in reverse while in a forward gear.

I wonder if Saab used Lucas electric stuff. Volvos did. All hail Lucas, the Prince of Darkness! Sound the Trumpets!
>I theorize that Volvo drivers are bad drivers, had a wreck, and now >want something "safe". Or just like ugly cars.
Well, they are safe, to the degree that any car can be safe. Something like ten years ago, about 10:30AM on a clear dry day, I was rear-ended on Route 128 (the inner ring road around Boston) while slowing down and moving towards an exit ramp. I was hit by a fellow coming off the corresponding in-ramp, acceleration to match speed with a space in passing traffic, looking in the wrong direction. Full speed impact - he never saw me. Nor did I see him, as he was in my blind spot. I knew I;d been hit, because nothing else could have caused that hard a shove. Both cars were totaled. But nobody was hurt. Neither windshield was broken, front or back. But the most amazing thing was that I did not have any whiplash - the Volvo seats were built to absorb the energy, and it worked. My wife, seeing her husband walk away from such a crash, promptly bought herself a Volvo. But she didn't like it all that much, because it steered like a truck (which was always true), and had too large a turning circle (which was a later development as the engine outgrew the engine compartment, limiting how far the front wheels could turn).

Saabs were great cars, between fires. Bad rivets on a fuse panel. I theorize that Volvo drivers are bad drivers, had a wreck, and now want something "safe". Or just like ugly cars.

I used to think of Volvos as an MD's car. But the Volvo used to be a Saab if they were a doctor of psychiatry

Good thing Teslas can drive themselves, as their owners tend to not be very good at doing it on their own

It's the same Panasonic 1865/2170/4860 cells as in the laptops. I stick with 1865s because of the larger surface area vs. energy density for cooling. My primary battery is pouch cells, but it's around 50% capacity and not able to catch fire. I am planning on replacing them with 1865 as well. An EV is like running 1000 laptops.
