Watched the Xpeng car driving experence.
It has two LCD panels, one for speed and the other for other uses.
I noticed some sub panel LCD for speed, but not ALL LCD.  What if it fails, how can one tell the speed from the console ?  I accept it as supplemental Digital speed, but not the MAIN and ONLY speed indicator
.
Guess the LCD display is really matured now.

I am not sure how the LCD panels are designed.. but I am sure it has a fail safe.  

i.e. may be the engine won't turn until the LCD panel is ready and on.  I drive one with LCD screen, and so far, it hasn't failed once because of software issues... i have seen it boot up one time as the engine turned faster than the LCD.. but the LCD speedo turns on everytime
