Did I miss the part where they differentiate between minor issues such as paint problems or YouTube crashing on the middle screen, and actual breakdowns where the car doesn't move when it should? According to the original article, they've included reliability issues such as drivetrain problems, irregular paint and broken trim in their ranking.

Losing in-car entertainment or comfort functions is still undesirable, but if given the choice I'd rather have a car that runs without music than a stationary car that lets me stream movies until roadside assistance arrives.
And concerning the former, the infotainment systems in most ICE cars are just as cutting-edge as those in BEVs. I would expect differences in quality/reliability between different manufacturers, but not within the same brand and model family where the only relevant difference is the engine.

(Edited for clarification.)
