Maybe the angle of the rear screen @Yorkman but it won’t prevent dew or damp. Can’t rememberthe last time I used used a rear wiper tbh, but I do use Auto Finesse CRP-K3 Caramics Glass Protection and water just sheets off. Its far better than rain x and cheaper if you get at the right place.
Nah.
Multiple issues here. First, angle of the windscreen doesn’t matter at all. If you look at a recent Honda Civic, they have a much, much shallower angle and still come with a rear wiper. That’s because the actual problem is the proximity to the end of the car. Your car creates a vortex when driving, which sucks in dust, water, dirt, spray etc when you drive. There’s no way around that. That’s why every car where the window is close to the end of the car (hatchbacks, SUVs, estates) comes with a rear wiper, and that’s also why for example 3series, or C-classes come with a wiper as an estate/touring, but without wiper as a saloon.
Water repellent doesn’t prevent your window from getting dirty either, if that was the case you could just spray the entirety of the car and never need to wash it again. Obviously not the case. It’ll be less dirty, but it won’t prevent build up. Our car is sealed in Autobrite Magiseal, and still requires reasonably frequent washes. After a run on the motorway in the wet, the car’s reasonably clean on the front, top and sides (as in, not in need of an immediate wash, not actually clean) – the rear is a disaster. And it’s pretty normal, too – on the bonnet, roof and sides you get airflow that pushes the water (and with that, most of the dirt) off. That’s why you you have loads of water beads on a stationary sealed car (ours looks like it’s covered in bubble wrap in the morning), and no water at all after driving for 500 yards, bone dry. On the rear, you don’t have that airflow, so the water (and dirt) relies on gravity alone to bead off. Which happens to an extent, but certainly not enough to keep the window clean.
It’s a cost saving measure, and imho not a good one. I like the MG4, if we had to order a car right now, we’d probably even go for one (or at least give it a shot, haven’t sat in one yet) – but that doesn’t make it immune to justified criticism. Saving money by omitting features that improve safety, even by just a little bit, is the wrong way to go at it. Give me the wiper and remove the bluetooth mobile phone key feature instead.
