AFAIK, Teslas just use huge arrays of 18650s. And it's well known that lithium cells can catch fire if they are crushed or pierced.

> AFAIK, Teslas just use huge arrays of 18650s. And it's well known that lithium cells can catch fire if they are crushed or pierced. Ah. So it's like gasoline then? https://www.youtube.com/watch?v=ISJdZD8POi8

Gasoline still requires an ignition source to catch fire. Lithium cells can spontaneously ignite when they experience physical damage.

I'm not saying electric cars are safer or more dangerous in the event of a crash (because I don't know the answer to that), just that batteries can and will catch fire.

I hate to be "that guy" but... Do you have a citation for that, by any chance?

Here's footage of the burning Rimac Concept One when Grand Tour's Hammond crashed it [1]. A Tesla burned down after a crash in Austria last year [2] 1: https://m.youtube.com/watch?v=T4sDy-zdV2o 2: https://www.golem.de/news/elektroauto-tesla-model-s-brennt-a...

In what way is that more vulnerable to fire than a gasoline powered car in a wreck? Cars catch on fire all the time.

I must disagree. India is a big market too. Then why didn't the multinationals come to share technology and set up manufacturing in India? I think it's got more to do with having decade long focus under a single leadership than have politicians floundering to get reelected every 5 years.

> Then why didn't the multinationals come to share technology and set up manufacturing in India? Because the indian government didn't demand it as a condition of entry like the chinese government did. Have you never wondered why western companies have to engage in 50/50 ventures with chinese companies into china instead of just entering china like they do every other country?

India used to have such conditions.

Look up Hero Honda, Maruti Suzuki etc. What happened was that the MNCs weren't interested at all. India followed with liberalization and removal of such "license raj" in 1991. Economy has done much better since.

I keep one in the pocket of my driver's side door and one in the glove box. The ones I have also have a razor for cutting through the seatbelt.

> in the pocket of my driver's side door After a roll-over, it won't be there and you may not be able to reach the glove box. If you have a center console, I recommend keeping it there (that's where I keep mine). If you're reading this and you don't have one in your car, buy one now. Here is a link for 2 for $10 (give the other one to your spouse/parent/kid/someone): https://www.amazon.com/dp/B01CQN0DDC/

Mine has velcro to keep it in place. Will it work in a roll-over? No idea, but yeah, definitely need it to be with in hand's reach for it to be effective.
