I tell people to try and make your ebike blend in with other regular bikes. Dont have wires and gadgets sticking out. Dont clean it. Make it not stand out. It's best to take the battery pack with you. I use 2 kryptonite U locks on my ebike. Never had a problem with theft or vandalism.
In my view, ebikes aren't supposed to be fast. 25mph to speed is fast enough for riding in a city. I am always worried about potholes. At least out in the country you don't have to worry about traffic. I care more about range than speed.
Tesla should downsize and focus on luxury electric cars and self driving technology only. They are losing too much money trying to go big. Back in 2010 nobody forecasted gas prices to be this low. Its hurt the entire EV industry.
