We need >2000 km ranges in one charge of electric vehicles for widespread adoption.
I think James May made a great point when he said it's not about range, it's about quick and ubiquitous charging. I wouldn't mind if my vehicle could only travel 300km... if I could have the confidence I'd be able to stop and top it up in just a couple of minutes no matter where I was. Faster charging would really make all the difference.
This is called a motorcycle! Mine can do 260-280km on a gas tank, still does huge trips. Once batteries work like gas, you're absolutely right.
