Condensation on the windshield.
This morning was brutal. About -7C and I've never seen such heavy condensation. The moisture trap-pillow didn't help at all.
Yep, one of my biggest bugbears. Never had a car which has such bad condensation on the inside of the windscreen.
What makes it worse is that there is no quick way to warm the engine up whilst waiting for the screen to clear as you can't raise engine revs via the throttle when stationary.
I don't know why the Jazz is so bad, maybe it does not auto close the ventilation vents when locking the car.
I also second the variable wiper speed, it seems difficult to get the ideal sensitivity for any given rain condition.
