Less is more. Inline 4s as they are is kind of ludicrous with the amount of perfomance you can get out of them with shit like the Ford RS200 Evolution getting close to 600bhp in the 80s and the newer Mercedes M139 getting close to 500bhp...at factory production baseline. As soon as you look at tuned engines you go beyond that and if your batshit crazy you can look at track made engines like Thor and Thor 2 which can go up to 3000bhp.
If you can squeeze that much out of just 4 cylinders going smaller in cylinder quantity isn't really a problem bar 4 cylinders being easier to balance compared to something like 3 cylinders. Beyond performance twin or single cylinders are just based on mere principle. Nothing comes close to reving single cylinder kinetically or audibly, it just pulls like a down syndrome's tard raging while enhanced by anabolic steroids. Two stroke twins have always been a based pick for bikes for similar reasons.

Again beyond perfomance, besides just make the cylinders bigger and half the time you won't get many opportunities to reach top speed in your car anyway even if it was a real concern. However you will certainly be doing more quick impromptu drag races at traffic lights when you come across a fag trying to fuck you around in another lane.
