Adorable, of course something like that will make you more cautious and it is always a good thing to be cautious and not to take anything for granted. There are some crazy drivers out there and sometimes accidents happen to good drivers because of animals that run across the road, or things that fall off of moving vehicles and sometimes because of glare. It must have been really unnerving being alone int he office when you really need to feel another human presence and probably could have used a hug. Human touch is very comforting and can be very soothing and helpful to calm down especially when you have the shakes after a trauma.
WE need to assume that the driver was wearing seat-belts and therefore there was a good outcome. We have heard of such outcomes in the past and seat belts saving lives, so please assume that it was the case in this instance and that even though there could have been some broken bones and bruising, or they could have walked out without a scratch, that the seat belts and air bags did their job and it was just a huge scare for everyone.
