It can be such an ADVENTURE at times!
I drive mostly in suburban type traffic, lots of stop/go stuff and when I get tired or am having an 'off' or worse day, I DO wish I could actually see where my feet are!
It's just a process of super caution, I guess. I schedule doc appointments after or before rush hours. I drive the less restrictive routes to offices, such as back roads - so I can pull over and walk around the car a few times to get some 'feeling' back in my feet. It can get scary at times? But, I appreciate the fact that I can drive [altho like a super-chicken] as I realize others aren't a mobile.
Just plan things out, allow extra time for delays [traffic and body wise] and be super careful. - j

I may drive like a little old lady, but I definitely am NOT!
