So, maybe I am the only one... But the LR4/Disco is the worst clearing windshield I have ever owned.
On my 3rd pair of wipers. Last set came from dealer. The speed of travel and temperature seems to play a big role. Winter time driving is a joke. The jets only shoot fluid on the bottom 3 inches of the windscreen when driving 80 mph, so the top is never cleaned. Also when traveling at highway speeds the wipers don't make good pressure with the screen and streak everywhere and flutter about when traveling across the glass. Least favorite thing about my car.
