Also, driving on a wet road with top down will coat the inside of the screen and dashboard with damp crud.
And yes - your lovely interior will not be best pleased. Neither will SWMBO
Coming back from a trip we had a memorable night time drive through Switzerland in light rain. We Had the top down and encountered the rain on the E13 some kilometres before the San Bernardino tunnel, we were keen to get home so we did not stop. At the speed we were doing and with the weight of the rain all the drops passed over the top without coming back on the inside of the windscreen. I have to say that the few heavy vehicles on the road gave us opportunities to pass; we wondered if they were in contact on CB radios? The rain stopped when we got to Lugano and we managed to find a pizzeria near Como that still managed to serve us a pizza after 11pm. 😋 😋
