So you want to play a racing game on top of pictures? Google maps isn't exactly filled with renders of buildings and streets, and copying the real world detail provided by those maps would be ridiculously expensive. Again, how many hundreds, nay, thousands are you willing to pay for a single copy? Keep in mind, it took Sega $70 million dollars for a much less detailed representation of what is essentially a single neighborhood in Japan in video game form (Shenmue). To have any semblance of the real world would take way more money than you can imagine to develop, and that's what you're asking for here. Unless you want every building and street to look the same, of course, at which point you stop having an audience. No one wants to drive on very ugly, inaccurate road that sorta reminds them of home. They could, you know, go drive a real car. Really, everything you're asking for can be done without using real maps, so why not just do it with courses designed by professionals to be fun? Heck, if you didn't base it on real life then you could practice any course in any weather when you want to, not when it happens by chance.
You do not have the right to never be offended.
