As a pedestrian, you have right of way over turning traffic. Of course, it's prudent to exercise reasonable care and not just assume a driver has seen you especially if visibility isn't good for whatever reason.

OTOH, especially at a busy intersection, if you're just standing on the sidewalk looking confused, a driver looking to make a turn is probably going to just shrug and turn right through the crosswalk. Some drivers will doubtless be overly aggressive or inattentive. But a random driver is also not going to sit there forever waiting for you to make up your mind about whether to cross or not.
