I clicked “Yes” because maps wouldn’t be a problem, but …
I’ve learned to be a cautious driver. Driving a car for 14 hours straight and getting tired or sleepy would be too dangerous, at least on the roads where I live. I’d want to schedule at least three rest stops, with coffee and food, maybe a massage!
Maps have always been best for me. Only once did my daughter turn on her iPhone and let Siri direct us. That worked fine, but I’m an old fogey and more comfortable with maps.
When I moved to rural Central Thailand 25 years ago, good maps were extremely hard to find. Navigating from incompetent oral directions was very difficult, and the cities are mazes with narrow lanes, etc.
And the signs are often very unhelpful. As one example, when I was a newbie and drove randomly around a nearby city to get a feel for it, I came to a 4-way intersection where there were three separate traffic signs, all very clear and unambiguous. The signs told me (1) Not to go straight, (2) Not to make a right turn, (3) Not to make a U-turn. What would you have done? The signs were all perfectly proper: straight would take me steeply down to the river to launch a boat; right turn would put me wrong way on a one-way lane; the intersection was much too cramped for any convenient U-turn. It seemed like a no-brainer: I turned left.
Wrong!! That takes you right into the afternoon market, so crowded that even motorcycles don’t attempt passage between the rows of stalls — they might make it, but it would be too rude. Spoiler: Although there was no indication whatsoever, I shouldn’t have been where I was at this time of day: My previous turn was wrong. The Thais driving in the city were almost all locals and very familiar with their city — They had no maps and paid little or no attention to traffic signs but certainly knew about their main afternoon market! (Nowadays the police place an appropriate barricade to block the relevant lane during the afternoon.)
