There are California Route 1's in Ontario, Canada!I stopped into see the Ford Mustang Mach E and here they only had the lowest range version. The 300mile range version is what Ford sells as the California 1 Trim and the salesman said it isn't available outside California. Seems dumb decision to me if true. All the Mustang models have lower range rating with similar batteries due to lower efficiency compared to the Tesla. For example if your 98KWH battery is correct, it would compare to my Model S 100KW battery which is rated for 402 miles at 100 KWH.
As far as the debate on real world numbers, that is unscientific comparison since the testing has no standards of measurement. A guy like Kyle Conner of Out of Spec Motoring never gets rated miles range because he has a lead foot and travels mostly at 85 to 90 mph with a roof rack on his performance M3 and non standard tires. By comparison, I drive for range at posted speed limits and keep the tires pumped to pressure and watch my energy meter so I do better than EPA. Once I achieved 430 miles range last summer. But choosing to do a battery full with speed it only got 340 miles range. So real world is not representative and can be anything the writer wants to make it.
I think the Mach E is prettier than the Tesla MY but that is just opinion. I also prefer the better engineering and efficiency of the Tesla over the Mustang Mach E.
