Many hybrids are not driven to max regenerative breaking. You need to drive and look ahead to make good use of the regeneration. Short distance breaking is still fast and using the discs.

Hard braking is an insane power. Eg. A typical 4,400 lb car emergency stopping from 80 mph has a braking power of 940 horsepower.

Hybrid cars have smaller motors, inverters, and battery packs - and none of those components can absorb 940 horsepower!

A 2nd gen prius battery for example has a max in/out of 30 horsepower.

Always sketches me out using regen for a serious grade decent while laden or towing. I have a sneaking suspicion that one day it's gonna error out and disable itself because too much power and I'll be down to just normal brakes.

It will disable itself if your battery is already full...

Some cars it's quite an abrupt change from the regen braking to the hydraulic brakes.
