I've been doing route planning for several road trips out of South Florida. EA coverage is pretty good if you stay on the major interstates, but it thins out quickly along even major non-interstate routes. In driving from Naples, FL to Asheville, NC, for instance, there are two legs where the distances between EA charge stations are well over 200 miles. With the Lucid's range, that's fine . . . unless you arrive at a station that is not functioning, which is not an unheard-of event at an EA charger.
Even though our Model S Plaid has significantly less range, we're considering taking it for the trip as Tesla Superchargers are now so ubiquitous (at least outside of places such as the Dakotas and northern New England) that you don't even have to do any route planning. You just get in the car and drive until you need to charge.
