Actually, those still are skills. You can't rename something to something it's not and then say "look, it has that something".
Drive +3 ... sure, that's an ability score.
Nope.
We're not talking about "ability scores", though. We're talking about "stats". A "stat" is any sort of number that you can use to quantify what something can do.
In some games, you just have very generic stats, and nothing more detailed. Old D&D, with its six ability scores and no skills, was an example of that kind of system. Nowadays, you mostly see that kind of model in rule-light systems, such as Maid.
Some games have basic stats, and also have a bunch of derived or secondary stats. This is how newer editions of D&D work, with both ability scores and specific skills that you need to track. It's also how
most games have worked since at least 1990, including both Shadowrun and the White Wolf system which derived from it, along with GURPS and BRP and Palladium and just about everything else I own.
FATE is somewhat unique in that it does away with the basic stats, and
only has those secondary stats, which aren't derived from anything. It's a fairly novel way of doing stats, but it's still just a different way of doing stats.
