https://en.wikipedia.org/wiki/Mount_Davis_(Pennsylvania) - 3,213 ft - highest point in PA

https://en.wikipedia.org/wiki/Tejon_Pass - 4,160 ft

Tejon Pass is on I-5 in northern LA County, and it is a huge trucking route. The grade is very steep between the Central Valley and the top of the pass, and is fairly challenging for trucks. There is no equivalent to those conditions in PA.

Also, if your impression of Tahoe is only the heavily touristed parts, your view is incomplete. The mountain roads in the Sierras have no equivalent east of the Mississippi.

looks like someone has never been to Pennsylvania.

Tejon Pass' major difficulty is the grade, and that's about it. PA may not have a highway that matches that grade, but many come close, and there are far more tight curves, typically far worse road conditions, and bad weather season is far more common than in N LA.

My point about Tejon Pass is that it's a steep grade mountain pass with heavy traffic including lots of trucks. There's no equivalent in PA.

Highway trucking will be the first significant deployment of autonomous vehicles. One of the big challenges is Mountain West interstates.

I do agree that the NE US is a proper testbed for bad weather city driving, since no West Coast cities have really that bad winter weather, I'm just objecting to the claim that somehow Pittsburgh captures all the challenging road conditions that autonomous vehicles will encounter.

I'm also thinking of the Virgin River Gorge on I-15 in Southern Utah, which isn't just steep and winding, but also extremely narrow and windy, and yet supports interstate speeds. I don't know of anything similar in the Eastern U.S; upstate NY and Appalachia have plenty of gorges, but most are local roads and aren't the main interstate thoroughfare between them.

Have you ever driven on 70 or 80 through PA? Because "steep grade mountain pass with heavy traffic, including lots of trucks" is an apt description of either route.

Definitely easy for a non-Pittsburgh to equate difficulty with elevation. Which ignores elevation changes, weather, sharp turns, tunnels, and bridges. Also a strange fondness for salt which generally makes things worse. Find a Pittsburgher who thinks driving in Tahoe is hard, even off the beaten path.

Personally I try my best to get as far off the beaten path as I can. Tahoe and surrounding areas is a cake walk compared to Pittsburgh.
