I have a MYP, and a Lucid GT (and also a R1S) on order. In my day-to-day driving (local), which is mostly 40-50 mph since most of the miles are local & snail-pace SoCal traffic, I often got the near or above the EPA range (low 300s). I guess this has to do with Tesla's awesome regen and the nature of EVs at low speed. On the weekend when we often head for out-of-town or Vegas trips, we rarely get beyond 240. Guess that 80 - 100 mph doesn't help

My neighbor's Audi eTron never gets beyond 200 miles range. Most of the time she got 150-160. This hinders her enjoyment of the otherwise fantastic car.
So yes, range matters. Not only how far can you go, but how often you have to plan for charging - whether it's SC or not, no charge is better than having to stop and charge. I would say for an EV, the most important factor is a range, and hopefully Lucid aces it.
