I live in Illinois and have seen a few Teslas on the road a long way from home as in Florida to Illinois and California to Illinois. The Tesla supercharging network has good coverage along the interstates and main highway systems as long as you don't wander too far from their charging network. Getting a charge isn't a problem although there might be a considerable wait time during peak travel periods.
Outside of Tesla, third party charging networks are a kludge. Electrify America seems to be doing a decent job of populating DC fast chargers, but they are way behind Tesla.
I don't see hotels/motels getting into the EV charging business on a grand scale. That is not their business.
“I don’t see hotels/motels getting into the EV charging business on a grand scale. That is not their business.”
I don’t know about “grand scale,” but it is happening to some extent on I-5 in California. For example at the Harris Ranch, hotel and restaurant complex in the valley, Tesla has a long string of its chargers set up. I assume Tesla paying Harris for the space on their property. Meanwhile, Harris can sell an overpriced steak dinner to the family of 4 while their Model 3 takes 90 minutes to charge.
