Car Travel Anxiety

I am a nervous passenger too, my husband drives fairly safely, keeps to the rules. but wrongly assumes others will do the same. I am constantly watching fir anyone about to pull out in front if us ( without signalling) and feel like a meerkat, on guard, watching and waiting.
It doesn’t help we were knocked across the top of a a very large bridge by a very large foreign lorry a while ago.
Have also stopped driving very far myself and nos avoid dark wet foggy winter nights.

Yes I know I can’t be responsible for other drivers. … I never used to be like this … it’s an age thing! Thank you all for your advice and wisdom!
