Regenerative braking only can recapture something like 2-5% of lost energy. The bigger factor is exactly what the other person said.

This is just not true. Regenerative braking is much more efficient than that.

I'm not sure where that number came from but according to Wikipedia the conversion from momentum to electricity loses 10-20% and the conversion from electricity to battery storage is another 10-20% leaving a theoretical recovery at 60-70%. In real world tests, Teslas recovered 20-32% range with regenerative braking, a far cry from 2-5% you cite. https://electrek.co/2018/04/24/regenerative-braking-how-it-works/
