What a sensational news and with little basis.
It is well known that it is better to load in the back, otherwise all diesel and gasoline cars would have put it in front, where any impact would mean an explosion or even worse, million-dollar repairs. Elon made the right decision and whoever does not know how to drive in reverse better not drive a car in his life.
I have already seen the new Tesla Model Y Juniper and it is a marvel, lower, with better grip and more aerodynamic to save energy.
I am looking forward to a smaller version coming out, it will be a success.
