well, I am going to chime in after reading through the majority. We are Arizona residents, drive I-17 quite a bit, to and from we see a bunch, a lot, and may I say too many people driving way to fast especially coming down the hills. We have seen a few over the years, mostly near the bottom as they "almost" made it. must have been going to fast and were tangled up with themselves on the side of the road or all over the road. Now I might add, we were recently in an accident in South Lake Tahoe, while we were in the fast lane, about 30mph, the lady that hit us came from the side merge lane, crossed it crossed the slow lane, T boned at an angle the front right of our truck, then I zigged into the center lane, then zagged across all lanes, with the final zig onto the curb / gutter / sidewalk. All was done in a few seconds and scarred the you know what out of us. Everyone was fine, just a lot of damage. Thankfully no-one was hurt, but a lot of inconvenience, cost, time loss etc. That happened on July 1, 2021 and we may have truck back next week, trailer will be probably another month. so for what it is worth, not all accident are the cause of the Fiver Drivers like us, but we have to be ready, prepared, and always cautious of what is happening behind, up ahead and along side of us. And we do the speed limit or less. Let the others go on and get there or not. Have a great day! ! ! Be Safe ! ! !
