Strange Times
She could have easily had someone else who signaled her to go forward and run his a** over. Among other possible scenarios. -shrug- As for her speed, she couldn't have been going at a deadly speed, elsewise her smooth stop would probably have cracked some of Mako's bones. Therefore, her acceleration time wasn't necessarily that long.

Notice that I said 'decent speed', not dangerous.
And for her to be signaled would mean that she was close to the location, but it showed her
several yards away before Mako made the movement to cross the street.
Remember, this is all happening in a quick time frame, just a few seconds. Not enough time for Mako to decide to cross the street, have someone signal Asami to go and to make it to his location by the time he entered her path. Highly unlikely, even for a cartoon.
