Also, with breaking recovering energy, this negates some of the issues too. The inertia is used to recharge the batteries, so the losses are from friction and heat losses. Obviously lighter is better, but a lot of the issues of weight on efficiency can be reduced. Weight is bad for safety though, so there is that to consider.
It sure does. But we have to consider that recharging is less efficient than not spending the energy on acceleration in the first place, so heavier EVs are worse off than lighter ones; it's not only losses from friction and heat losses - those come on top.
And you're spot-on with the danger that comes from weight; being in an accident with a lot of kinetic energy that needs to be absorbed is not great.
