Is できる always used with が？


So I'm studying and I ran into an example that stated to go from a (noun)suru
to (noun)dekiru is this:

私は車を運転する －＞ 私は車の運転ができる。

Why isn't 私は車を運転できる。




I wouldn't say always. I think the construction Xができる is more or less a fixed
expression for "being able to do sth."

車の運転ができる sounds more like "I can drive" in the sense of "I have a driver's
licence and know how to drive". It is unmistakably a statement about me.

車を運転できる might be interpreted more circumstantial, like "The car is drivable
and I can drive it (now)". It might be a statement about the condition of the
car.
