A few years ago, late winter, we were driving west on I-40 thru the Texas panhandle and hit a wall of the thickest fog we’d ever seen. You couldn’t see the side of the road, let alone any offramps...just the vague glimmer of tail lights ahead; traffic didn’t slow, so we white-knuckled it for close to a hundred miles - virtually blind and going 70MPH, praying that somebody coming up from behind didn’t run through our tailpipe.
I cannot think of anything that would be scarier than that, knowing you can’t just pull over, or stop for fear of cars hitting you.
That’s a recipe for a major disaster; glad you made it thru. I had a similar experience back in the 80s on I-78 west from NJ to PA, in a blizzard. I had a death grip on the Jeep’s wheel even after I got out of it.
I’ve done that on a motorcycle. Just following the faint red lights ahead since it was even more dangerous to pull over and wait.
