Luckily, no one was seriously hurt. According to the female driver of the Lexus, the gas pedal stuck. At the end of the day, this turned out as well as it could have - all things considered. In addition to no one being seriously injured, there was no structural damage to the building and the car was relatively undamaged. My dad thinks that the 2,000 pound medical records cabinet that was located between the parking lot and the receptionists stopped the car and probably prevented it from plowing completely into the hospital (and really hurting someone).
The fireman cleaned up the site of the accident. News 11 and News 5 were there on the scene. News 5 interviewed my dad and had a reporter broadcasting live from their hospital on the 5 p.m. and 6 p.m. news. Julia wanted to see Grandpa and Grandma talking to the fireman and the tow truck a few times on TV...and then wanted to call and talk to them on the phone.
