I am concerned it may be too difficult to negotiate the route out of the airport to get to country type roads. The traffic also seems to have to go through a long tunnel which worries me.
It depends on where in the UK you want to go and visit. Make sure you either bring a satnav or hire one with your car. There's a good motorway system easily accessed from Heathrow airport and depending on where you're going, you shouldn't have any tunnels. If you're going to the southeast, you may have to go through the Dartford tunnel. The worst thing about that is the traffic! The M25 can be absolutely gridlocked at times so try and avoid it then. If you're going into London, I wouldn't bother with a car. You have congestion charges, no parking, lots of traffic...:/ Go onto the aa website and ask for directions to where you want to go. They're pretty detailed. Yes, the roads are probably smaller than you're used to and yes, we drive on the left, but you'll be in a right hand drive car so all should be well. After a long flight you may be better to stay nearby for the first night till you get accustomed to the car etc. Have fun and relax, you'll be fine. over 6 years ago
If you are hiring the car for more than a week you'll be cheaper and better off buying your own sat nav. These car hire companies charge stupid amounts per day for the luxury.
But yeh, driving in the UK is easy, as long as you know where you're going. Like any city really! about 6 years ago
