If they are going to make call backs to "Sonic R", then I hope they have a mode to play without cars. Sonic R is one of my favourite post Mega Drive Sonic titles. It was the only 3D game designed by Yasuhara and it feels a lot more like a classic Sonic game then anything that followed from Sonic Team. I know it had lots of problems, but I'd love it to get a proper sequel without any of this car nonsense. Even though Sonic didn't control that well, I always thought it was creative to put him on foot. Having him in a car feel 'less creative' (even if it controls better), so the option of ditching the car would be a nice touch.
