The size of the coach also matters here, at under 30 feet it is somewhat practical to just drive the motorhome places. A standard full size parking space is 22 feet long, my 28 ft Safari Trek (29'5" bumper to bumper) with a 178 inch wheel base will often almost fit in a standard parking space if I can back in and overhang the curb. In the 12,000 miles I have put on my coach since buying it a couple of years ago, I have rarely not been able to find a parking option when needed, though there have been places that I have bypassed due to feeling it was not worth the effort, and times I have stayed at campgrounds vs making trips to a store, etc. We have also used Uber, rented a car, as well as used campground provided shuttles, even once a public trolley system that picked up in front of the RV park. Eventually we will likely setup a TOAD, and when my wife needed a new car earlier this year thanks to a teenager in a Yukon running a red light, we bought one that can be adapted for 4 wheel down towing, though for now our solution has been to plan trips to places where we can either use the coach, rent or use Uber, etc. Sure this means that there are places that we don't take RV trips to, but we will worry about those places when we run out of places we want to go that can be done without a TOAD.
It seems whenever this topic comes up someone makes a statement like Gary does above about the overwhelming majority towing a car. I don't think this is true, I live in a small town next to the intersection of 2 federal highways in Louisiana, so lots of RV's pass by in front of my house, and I can confidentially say that the majority of the class A motorhomes that pass by are traveling without TOAD's. Sure depending on the season a lot of them may be going to the lake for the weekend, but that still counts as traveling. I keep planning on setting up a web camera and counting them, but a casual estimate would put somewhere between 1/2 and 2/3 of class A's that pass by my house don't have TOAD's and something over 3/4 of class C's are without TOAD's.
