330Wh???

My first gen Insight has (had, it's lost a lot of capacity) a 936Wh battery, and filling that braking downhill was far from impossible.

But.

A 5500lb truck at 30mph has about 62Wh of energy available.

A 5500lb truck at 60 mph has about 249Wh.

You're lucky to get maybe 50% of this back from regen braking. My guess is they're not expecting to get even this, since the weight of the truck will necessitate the friction brakes on most cases. Still, for trucks with such a high base price (we're not talking a Nissan versa here), you would think they would have at least double that.
