Motorway driving, never liked it even when I passed my test at 17, last resort really for me - has any-one tried M25 round Heathrow !!!
Severely claustrophobic - MRI Scans (had 3, only in up to chest), the thought brings me out in cold sweats. Lifts as I was stuck in one but preferable to going down an escalator
Heights, can't even get one rung up a ladder (used to climb trees, ladders) but I did London Eye despite my worst nightmare being heights & water - I loved it
Multi-storey car parks, it's not the parking it's a safety issue when I'm on my own.
Country roads - I just love them, where I live there are some lovely single track & narrow roads although I do avoid them during the Summer (& other holiday times) due to "tourists" who don't know how to drive on them & panic when they meet another car !!
