It doesn't even have to be driving, forklift does apply, but so does a crane (a lot of factories have gantry cranes for moving stuff), or even operating machines that require your attention like manual lathe or presses.
A car is just most common, and most likely to cause harm out of those if you get dizzy, but you can still hurt yourself with plenty of other machines if you're inattentive, sleepy or dizzy.
