Is 50% tint actually enough for Abu Dhabi summer or should I just go darker and risk the fine-Forum-Culture Informatique

Just moved here from the UK about two months ago and my car has whatever factory privacy glass came from the dealership back home which is basically like having a clear fishbowl compared to what everyone else is driving around with and my left arm is already two shades darker than my right from the morning commute. I’ve been looking into getting proper Car window tinting Abu Dhabi  done but I’m honestly so confused about what percentage is actually legal without getting stopped every other week because I’ve had colleagues tell me they’ve been running 30% for years with no issues and others who got a ticket the first day they went below 50. Also I keep seeing these ceramic options that supposedly block more heat even with a lighter tint and I’m wondering if that’s actually legit science or just a way to charge double the price for a slightly better looking movie. I don’t want to be the guy sweating through his shirt at the traffic light but I also don’t want to be the guy peeling off his tint at the inspection center with a hair dryer and a credit card while a policeman watches. Anyone have a recent experience with what’s actually being enforced these days and whether it’s worth paying extra for the fancy heat rejection stuff?
