I'm fortunate enough to still have my copy. And it runs pretty well in DosBOX. Which is good, the only thing holding back the release is presumably a licensing agreement.
I was a huge fan of racing games back in the 90s and one of my biggest complaints was always that they forced you to go around the track and prevented you from leaving it. BRR was different. There were a few sanctioned short cuts that players could take and even on some levels, most notably that one water level with the swamp boat thingies, you could completely leave the track.
The use of recording session outakes for most of the sound clips was an epic decision though.
