Progressive form of “have” indicating possession

Question

I know that normally I cannot say "I am having a car", but is the following correct?

Having a car, I decided to drive there.

I am fine with having a car but do not expect me to drive.

Answer 1

You're right that we can't use Continuous forms of "to have" (= to possess) as predicates (finite forms).

But in your sentences there are nonfinite forms:

Having a car, I decided to drive there. (The Present Participle)

I am fine with having a car but do not expect me to drive. (The Gerund)

So these sentences are grammatically correct.
