Can I use brake energy recuperation while driving on the highway?

I've been reading about the Audi e-Tron's brake energy recuperation system and I was wondering if it is still effective while driving at high speeds on the highway. Would it be worth using in this scenario?

Yes, you can still use brake energy recuperation on the highway. However, the effectiveness may vary depending on your driving speed and the traffic conditions. In heavy traffic, it may not be as effective as on open roads.
