Horses can in theory, go anywhere, but in practice it’s not advisable, at least at more than a trot. If you’re going at a canter, or god help you a gallop and the horse’s foot finds an unseen and unexpected hole, stone, etc... you’re going to be in serious trouble and so is the horse. Generally you only ride horses at high speeds on well worn and known trails, or roads. So yeah, a horse is better off-road than a Model T, but I’d rather walk unless I know the trail. Trotting for long periods is an athletic thing if you’re riding English, and torment on the groin otherwise. All in all, riding a horse for long periods is not easy unless you’re very used to it, and physically fit. Remember that at the time most horses weren’t being ridden, they were pulling carts or carriages, and they’re not exactly off-roaders either. Fuel was definitely an issue, but you could just carry tins of fuel and the car wouldn’t mind carrying them. Carrying food and water for a horse is no joke, and horses also need to rest. You also don’t have to take the saddle and bridle off a car, wash the car and brush it down. Horses really are a lot of work, especially if you’re working them hard. Remember that work also comes at the end of a long day in the saddle, which is hard work for you, especially if you’re beating a trail at a trot. Parking... I have no idea about the logistics of parking at that time, so I can’t say.
