I had some experience with RTK and sensor fusion about 13 years ago on a college project. At the time the only people that were using RTK in real world applications were tractor companies because it kind of matters that you're precise when seed drilling. I'm not sure how far RTK has come but it had pit falls back then like base station drift when the set of satellites it saw changed due to them going over the horizon.

Tractors don't go _that_ fast but I'm not sure I'd rely on it in an actual car for anything but slightly better GPS.
