I own a '23 Air Touring with 20,000 miles on it and just completed a 1-way 1,100 mile trip down the east coast. I have seen very similar charging speeds. The highest kW I saw the entire trip was about 200 kW at an EVGo station, and only for a brief period of time. And due to the lack of chargers where I am (the nearest L3 charger is 50 miles away), I attempted to charge to close to 100% and saw a drop to 9kW at 95% (at which time I gave up trying to get more charge). In cases where the car was at a relatively low state of charge, a message on the dash would state "charging speed limited by charger." At higher states of battery charge, this statement would not be there and thus I assumed the charging speed was limited by my car.
I have to smile when I hear Peter Rawlinson talk about only needing an EV with 200 miles of range because, in reality, that is what I have. On road trips, traveling at 75+ mph with the heat or AC on, I typically get about 2/3 of my specified range. And then if I charge to 80%, and take into account that L3 chargers are fairly spread out, thus requiring that I stop sooner than I would otherwise, I find that I'm stopping about every 200 miles.
BTW, with every stop I made, EA worked flawlessly in recognizing my car (my free period expired recently so I'm now paying, and the Lucid App used my credit card on file). A few stops at EVGo also worked flawlessly (I have an account with them as well).
Overall, a pleasant drive, other than some horrendous traffic. The car is supremely comfortable and fun to drive. We could have taken my wife's 2025 Cayenne which has a range of about 500 miles on a full tank of gas. However, I would much rather drive the Lucid!
