Computer science is concerned with the making of computers, their
programming, and their usage.

Computer scientists also recognize that the difference between what
is “hardware” and what is “software” is essentially arbitrary.

There is no analogue to this in car engineering.

You have complexity theory. But there is a world of difference between
that and knowing how to write actual programs.

Again: one is part of maths, the other is part of computer science.
