Must say I love my little car. Always used to say I felt like a tortoise, which the car as my shell. Drive all around London (avoiding rush hours, where possible), quite happily. Not as happy about night driving, except on roads I know pretty well.
For past two or three years I have been using the coach to go from London to visit daughter and family in Somerset. However, have now decided that the faff of getting from my house to Victoria Coach station is just too much for me. (walk to bus stop, bus to underground, underground train, then walking from there to coach station and sitting and waiting at gate). It is actually easier to return to driving this distance, during the day, and being prepared to take breaks as I feel I need to at service stations. At least, that way, I do not have to worry as to how heavy a case I can manager, etc.
These days on motorways I tend to stick to the inside (driving lane) at about 60 mph. Best for fuel performance, and quite relaxing. I always have audio books in the car and use these on long journeys, so that even if there is a traffic hold-up, I really do not mind.
