The startup lag time has me a little concerned. I hope it is a software issue they can address over time. I have been driving a Tesla Model S for the last 8 years and the delay the getting in to drive is almost non-existent. There are times where it can take a few seconds, but its nothing really significant. Early on Teslas took a little while to fully boot up as well, but the software improved over time.
I cant help but picture Apollo 13 when thinking about Lucid engineers trying to improve the car the boot up. LOL.
