For most purposes, though, they're nearly completely interchangeable, from a subjective perspective. If your reaction times massively increase, and the speed at which you can move does similarly, then that has the essentially same end result. Even from an outside perspective, they're difficult to tell apart visually. That there is ambiguity over what exactly Weiss did further supports this point. Unless the show plays up the subtleties, then they're effectively the same thing. Note that I'm not saying that they are the same thing, merely that they're really similar. You can tell by the decay of radioisotopes and such, or even simple clocks, which is which.

I shall illustrate with your cars. Again, same scenario, but this time, car two accelerates time locally around itself by a factor of 2.5. It therefore reaches the same speed as the first in four seconds. From a perpective only considering the cars, the same effect has been achieved. But of course, if you've got clocks in each car, it's easy to tell what happened.

I will admit it's possible, under the pure Haste interpretation of the event, but given that there's a clock present in the glyph when it happens, it could also be time wonkiness.
