I would actually say those numbers are unexpectedly high for Formula E. A "new" series with comparatively no history, no mainstream (= main news) coverage and same cars for everyone (afaik, haven't been following) and not being the "ultimate" fastest car like F1.

As to the vid:

- without sound it looks like normal R5 vid, a bit slow (looks very slippery though)
- until like 6s in the sound is very much like a normal R5 too
- up to like 12s and out of the corner the sound is different but ok, after that it's too quiet

- it could use some sound improvement at longer distance so that spectators can follow what the driver is doing (on throttle, on brakes etc..) and for spectator safety, this has been mentioned before whether the cars should have some sound generator that "indicates" throttle.
