The key thing for a smooth ride is minimizing unsprung mass (I.e. the mass not supported by the suspension). This mass needs to be able to bounce up and down quickly as you go over bumps. More mass means stronger suspension.
US EVs have massive weight, but the European ones do not, and Regen means smaller rotors.
Only the US market is obsessed with stupid ranges that no one does daily. US EVs are just carrying around 1000lbs of excess battery, which takes energy.

Wheel hub motors have been around for a while but they have always had ride problems.

You're right but another key thing for a smooth ride is large sidewalls and how many cars have thinner ones for aesthetics?
Many people also drive vehicles with solid axles that are very bumpy.
Cars don't have to be optimal in every category, maybe this one will find a niche.

Taller tires are coming back. Manufacturers are fed up with warranty claims.

So true and (imho) thin walls are ugly. And less efficient for an EV.

Bigger wheels for bigger brakes, which EVs need because of their massive weight.

BYD Tang (EU market) 380kW, 108kWh, 2600kg
Funnily enough, i didn't cherry-pick the biggest one i could find—i cherry-picked the one i saw that said "EU market". lol

Agreed, I'm curious to see if they've solved it and how if so.
