Here in the Caribbean, weather can change in the blink of an eye during the summer months and I've been caught in downpours several times. As others have said, at speeds above 40mph or so, it's amazing how much rain just blows over the top but the leaks at the windshield and door gaps do eventually cause puddling in the footwells. My wipers do help and the worst part is definitely the drip onto my right leg (right hand drive).
The carpet and leather seats dry up just fine with no lingering smells or issues like you get in a closed car. I have a soft top and I only put it up when I see a rain storm approaching, but if I'm caught driving, the soaking I'd get while stopping to erect it makes it worthwhile to just keep on going. I have stopped and put the tonneau cover on to wait out the rain when a convenient spot is available. It's all good - I had a kniption the first time it happened, but after that it just became part of the Cobra adventure.
