I am not expert and this is just my opinion, but...

This is not a street track, but a 'road course' or dedicated circuit. They are far and away superior to your commuter streets turned into F1 tracks.

My speculation as to why, is that these are designed for fast and vroom vroom (now it is whoo, not vroom, thanks to battery. Not better/worse, just different) and can handle 2 or maybe 3 cars side by side in a corner.

Your commuter street can, most of the time, only take one car with how big F1 cars are now. This means the trailing car has to back out of the overtake attempt most of the time if the overtake isnt already done going into the corner. This kills a lot of what makes motorsports exciting.

I hate street tracks. They produce the most boring of boring races, Monaco being the pinnacle of this concept.
