1. Considering the abysmal velocities of the primary weapons involved, I'll hazard a guess that vehicle combat taking place at anything like 275m is the exception, not the rule. Regardless, avoiding shots with nearly a full second of travel time isn't exactly groundbreaking nor is it unique to the Magrider. 2. Acceleration is explicitly needed to calculate the displacement of a body, which is certainly a factor in deciding whether or not a shot can be avoided at all. If you can only shift your 7m wide body 2 meters in a given direction before the shot reaches you it doesn't matter how "pro" you are or how many refire rates you have memorized - all the other guy has to do is aim for the center of your tank and he'll hit you every time. This isn't a variable you can just ignore.
