Plugs: UK standard or something similar. I hate those US plugs. Jesus Christ I always feel like I'm going to get a shock when I plug something in. I don't know how they can simply accept these sparks when you plug something in or out.
Chargers: Apple should be forced to use USB-C.
On-screen keyboards: (For logging into Netflix or whatever on your tele) Should all be QWERTY. None of this some using ABCD sh*t
Shops: Prices on items in shops should be the f*cking price you pay. (I'm looking at your state tax, America)
Driving: Driving on one side of road (I don't care which, just f*cking pick one)
English spelling: Should be UK English spelling
Daylight Savings Time: Get rid
Measurements: Should all use Metric system (And this is coming from someone who grew up in the 70's). Weights, Metric system too. WTF is a "Fluid Ounce"? Are there 16 fluid ounces in a fluid pound? 14 fluid pounds in a fluid stone? Temperature measurement too. "30 degrees outside" "Nice" "Are you nuts? Water freezes at 24 degrees!!!" "WTF?"
We absolutely have to have driving on both sides of the road. Otherwise there would be carnage.
It would also be a total waste of 50% of our road space.
