We can usually compensate for the lack of starting, and maybe slow down a little in the turns because we don't want to break the dishes as they fall out of the cabinets. Increasing following distance from a car's 2 seconds to the recommended 5 seconds as specified in commercial drivers exams, will definitely help us have enough time to slow for a stupid driver who cuts off our path. But then we get frustrated when people continually fill the hole that is created when we increase this following distance. This forces us to move further and further behind. Even driving safely, there are still times when we just have to lay on the brakes and get stopped.
Emergency stopping a motorhome is tough.
The most difficult stopping situations happen at highway speeds going down steep grades. Momentum and gravity combine to provide a real driving challenge. Dingies simply make all stopping situations more difficult. Personal safety of those riding with us or driving near us is of primary concern, but there are at least two other concerns to deal with. Those are legal and financial.
