This is true to some extent, but the biggest burden on automotive computer performance is actually safety compliance. Most modern automotive ECU's have an entire core dedicated to cross-checking the validity of the other cores execution. Protection against an extremely hostile EM environment ends up resulting in very low clock rates (150-300MHZ). And software safety mechanisms mean, at some times, 50% of core allocation could be consumed by safety related code.
