Admittedly, they can start to look tacky if the commercial density gets too high.
That pic is a bit of an extreme example. It is Breezewood PA when I-70 meets the Pennsylvania Turnpike, now I-76 (still tolled). Federal funding back in the day did not allow a direct Interstate connection to a tolled highway, so all interchanging traffic between two major highways is routed through a couple of short surface roads. Those surface roads are now actually designated as part of I-70. It's also a bit of a compressed shot.

True, the service centres are good for a quick in-and-out. But if you want to give the kids a break with a bit of a picnic and leg stretch, stretch out your legs, the dog, etc. they are an ocean of hot pavement. As discussed above, many to have picnic areas but they are not very inviting and treated like a closely guarded secret.
