Capitan's timed automobile aquisitions are kinda, extremely tight?

So, done several of this carjacking missions now, when they're timed, I usually get within like 200-300m away from the target until time runs out, even if I've literally leaned on the pedal and had straight road with next to no traffic on it.

I can only assume there are more optimal ways to get to the destination than what the "gps routing" is giving me, unless I just plain old need to "gid gud".

Give it to me straight, are these just brutally tight timewise or do I just plain suck?

I wouldn't usually care for optional things, but El capitan berating me each time is getting old.
