Just a tip to help others with tailbone pain. I had to do a 220 mile round trip today but, after reading this tip on the 'net, took a bath towel and rolled it up into a sausage. Put it under the coccyx cushion on the driving seat and, hey presto. Not nearly as much discomfort as I had feared. I think the coccyx was more or less suspended in mid air. Had to adjust the internal and wing mirrors and my head was nearly touching the car roof but it enabled me to do the journey in relative comfort.
