Not very many NASCAR tracks are road tracks, looks like 5 out of 29. I don't believe NASCAR has ever (or at least in the past decade or so) raced an actual street course though. E.g. similar to the Monaco GP, Montreal GP or for ALMS, Baltimore GP.
Isn't the lack of fuel gauges more due to them being inaccurate if you are at a 30 degree slant and back to level? I believe they use fuel pressure gauges to indicate if they are running out of fuel.
Well, NASCAR only has 4 dates at 2 tracks with restrictor plates, but a lot is made of them. Cup has two course: Watkins Glen and Sonoma which each get 1 race. I do wish they would move one to the chase.
I cannot remember Cup racing a street course, but the Nationwide did in Canada and the Trucks raced on dirt[1] this year, so they might be a Cup date in the future. Nationwide ran a road course in Mexico City, so that might be a possibility for Cup.
They just don't let drivers have much info or else they'd let the drivers have a speedometer. Heck, they've banned cellphones in the car since that could be used to get performance information.
1) a Cup race on dirt is a scary thought, pitting would be odd
