My guess why drive in the rain with the top down point blank. Just does not sound like a good idea to me at all

^ its for when it starts pouring suddenly when you're already driving.

stopping and putting the top up doesnt make sense if you can ride it out.

imagine a passing rain cloud... if you were to stop put your top up you'd get wet in the process of slowing down approaching an overpass.

just speed up and hold it until the rain stops.

Well for me i can't put a top up either way so inless the weather looks perfect and i check the radar i don't take the top off. But it does sound like fun to drive top off in the rain

If you drive really fast in heavy rain, you'll stay dry after you flip the car over....

From a purely scientific perspective, that is not entirely true. I watched a segment on truthbusters about something similar. They tested the theory about running in the rain vs walking in the rain. After their own tests, they found that running in the rain made you more wet. You will actually pick up more rain by moving forward at a faster pace than you would by moving at a lesser velocity.

This is something that has been argued back and forth for years really. I also found an interesting calculator that allows you to estimate just how much rain will fall on you if you are walking or running. Who knows, you may be able to plug in the dimensions for an S2000 in there and see your optimal travel speed to get the least wet.

I have driven through a fair number of rain storms and found that no matter wet, there will always be some water that gets into the cabin of the car.

Here is the link to the calculator: how wet will you get?
Posting that is not well thought out. The reason is: you have the body of the car and an angled windscreen in front of you. As long as you're going forward faster than the rain is falling down over the open area of the car, it won't get in from the top and obviously not from the front. I think the issue is dripage from around the windows.
The reason it worked the opposite way in the Mythbuster's experiment is because the front of their clothes got wet and absorbed water... not something that's going to happen when you're moving forward with a windscreen in front of you.

My own experience has shown that if you bring the window down about 2 inches, it will disrupt the airflow enough to where the water wont track much up the glass, but will just spit off the a-pillar. It will still get you a little bit, but nothing like if you have it up (spraying into you from the top edge) or down (spitting at you from the pillar)

Take it for what it's worth.

The most disturbing thing in this thread is the repeated suggestion of driving 70-80mph in heavy rain. Seems like a lot of our members can't handle 30-40mph with wet pavement. Why would you recommend they speed up in a downpour?
