I race both on-road and off-road. You're absolutely correct about off-road being more about setup and throttle control, but on-road is vastly different.
In on-road stock racing, the most important item for speed is the batteries, followed closely by the motor, then setup, then throttle control.
Serious on-road racers (those just short of the "pro" level) will only use the very latest approved cells with the highest matching numbers they can get. The minor differences in voltage actually means something to people who can run 40 laps in a row with less than .2 seconds variance in those laps. When you get to be that good, you can tell the difference between 1.222 and 1.225 volts/cell in a matched pack.

On the original topic, one thing to remember is that ROAR doesn't actually "BAN" anything, per se. What they do is choose what technologies are approved, creating a list of what you can use, based on lots of testing and 'encouragement' by various manufacturers.

Most tracks only loosely follow ROAR rules anyway, at least for club racing. I've never heard of a track that didn't allow lithium-based batteries in at least one class for club racing.
When a ROAR-sanctioned event comes to town, however, they should definitely abide by ROAR rules.
