It can also do time travel.

Take-away 1: Electric cars emit 20% more micro-plastics from tires than do ICE vehicles.

Take-away 2: Electric cars are not the solution to climate change. Whether it's a 2000lb ICE vehicle, or a 4000lb EV vehicle, it takes a lot of energy which has to come for somewhere, and a lot of material that will have to be mined, and then eventually disposed.

But is it strong enough to make a space elevator?

How are they for coming off ? The various reinforced tires I've tried (randoneur, gator, 25mm) are really hard to put back on. Like you peel the skin off your hands trying. I've notice that most tires, even cheaper ones, don't give you trouble for the first 500 miles. So have gone back to a medium grade tire that doesn't require special tools to replace.

 

Researchers at Virginia Tech have found a way to upcycle plastic into soap. Around 120 grams to 130 grams of plastic can make 100 grams of soap.
