I've seen recommendations on these forums for getting a WiFi hot spot with rental car, and this would be ideal for us as we'll be driving for 9 days mostly in relatively remote areas of Scotland. However, none of the car rental companies I've tried offer this as an obvious choice on their websites. They have other optional equipment such as child car seats and GPS units, but I have not seen a WiFi hot spot.
How do you request it? Do you have to call them and talk to a person? Are there only certain companies that have it?
