Excellent points, Rashmee. My kids learned how to ride bikes in preschool, but rarely used them as they grew up. I thought that odd, but now find out it was because riding was scary dangerous. We live in a nice neighborhood with wide streets and no sidewalks. The residential speed…

This was an interesting article, but incomplete. First is understanding the difference between Tesla and established vendor EVs.
