Yeah, the kinetic energy associated with a running engine (flywheel to entire vehicle mass) makes it rather difficult to stall from a single cycle problem, especially given that it consistently recalculates and checks everything multiple times before the timing signal is sent.

The engine feels like it’s running fast, but it’s really slow compared to ECU’s ability to observe it and respond to it. A single missed signal would just result in a misfire.

Like the notoriously hard to stall Citroën 2CVs and Dyanes, where roughly a third of the total weight of the engine was the ridiculous flywheel.

They could chirp the tyres in first, second, or third gear if you got all that mass spinning fast enough, not from power but from momentum.
