I am 6' 2' (188 cm) tall and drive several vehicles with cruise control: a Subaru Outback and a Honda Insight. The Insight definitely has limited leg space.
For light traffic conditions, it is usually safe to put the right foot on the floor. Often I cross my legs for a few minutes every once in a while which is a very comfortable contrast to feet on the pedals. If emergency stop conditions occur, both feet are needed pronto: left for the clutch pedal and right for the brake pedal. Starting from legs crossed on the floor, a reaction couldn't be much more than 0.25 seconds since there is no real weight on the feet. If driving conditions deteriorate, I move my feet close to the pedals defensively.
In moderate or heavier traffic conditions where braking is much more likely, I rest the outside edge of my shoes on the walls beside the pedals. At least on my vehicles, this is quite comfortable. Alas, I once drove a (forgotten) rental vehicle where there was no good place to do so for the right foot.

Two things come to my mind:
Too small car: if you're tall, the car may simply not be big enough for you; I always rest my right foot on the floor and have driven for 4+ hours without experiencing any noticeable inconveniences. You could also try driving SUV since they tend to higher chairs, which gives you more space between knees and floor.
Wrong sitting position: if you're sitting too close the pedals, you'll naturally not have enough space left.
