It does--noticeably.

As far as cracking your head on the roll cage, I assumed that since the structure is stronger, it would crumple less around the cabin and you actually would be safer, like this guy...

IF you have a helmet on, and are in a good supportive racing seat, and you have five- or six-point harnesses on that are snugged down tight enough that you cannot move your torso enough to reach the radio, or to turn and look over your shoulder,
then you will be safer in a roll-over and possibly other collisions. If you are wearing a stock seatbelt, you will move around in the cockpit an awful lot--more than enough distance to smash your head into the top brace shown in the video, for instance. But stock belts let you tune your radio, look over your shoulder to back up, turn your head to check your blind spots, and all of those other things you really do need to do when driving on the street.
This is yet another way that a race car is different from a street car, and another thing that applies to the one but not to the other.
Roll cages are
DANGEROUS on the street.
