Regenerative braking isn't hugely efficient:

Conclusions?
For one, we can document that electric regenerative brake systems are able to recover 55% of the vehicle's kinetic energy. I suspect it would be easy to get over 70% if we changed the gearing to improve efficiency.
The real lesson is that if you want to recover more total energy, start by being more efficient in translating the electric energy into kinetic energy.
That is where the biggest losses are.
