Here's what happens when your Tesla Roadster (or any EV) reaches the end of battery life

I thought the same thing about battery tools when they first started to show up. Never replace corded tools, not enough power, to short battery life. Now look what happened. Everybody uses them, contractors have them, they are powerful and charge faster.
The problem with waste, what to do with them has to be addressed, but im sure that will be taken care of someday
Dont get me wrong im not in favour of EV, I dont see the advantage and have zero desire to own one but I still think someday there will be more of them on then road then internal combustion engines
They also have problems with lithium ion fires in some instances. It's been well documented. That said, I have several. I just keep my fingers crossed. One tool I have, an electric pole saw I have had five or six years. I've charged it......wait for it.......TWICE. I can go grab it right now and cut small trees down. Put it up and six months later do the same thing. Progress has been made, I admit.
