EV Weight

I thought this bit was important:

However, in the longer term, the assumption that electric cars will always be heavier is also open to question. Auke Hoekstra, an energy transition researcher at the Eindhoven University of Technology, estimates that batteries are cramming twice as much energy into the same weight every decade. If that continues, the weight problem will disappear before it has started.

That ties in with the general rule (I'd heard of) that outside of technological leaps, battery density (weight and volume) was typically improving ~5% per year.

Lots of man-maths here, but that also suggests to me that the increased weight limit for BEV trucks in the EU/UK of 2tn, might not be needed in 5-10yrs, assuming a long range BEV truck has a battery weighing in at 4-6tn. I mention this, since it's the max weight vehicles, such as trucks, that do pretty much all the damage to our main roads.
