One of things I've had to learn to do when getting into the Lucid is to hit the brake pedal immediately, which starts the power-up procedures. By the time I fasten my seatbelt, put on sunglasses, open my ever-present soda, etc., the car is usually ready to go.
However, rainy season has begun in south Florida, and last night leaving a restaurant I got soaked in a sudden drencher (meaning I didn't take my umbrella) while waiting for the door handles to extend. Our other cars with proximity sensors (Honda Odyssey and Tesla Model S) open up much quicker.
I also agree with another poster that it's ridiculous to keep the backup and overhead cameras on until 18 mph. I have to hit the "X" button to turn them off manually in order to get to the Homelink button to close the garage door. They should disappear when you put the car into drive.
