When such a terrible accident occurs it is only natural to wonder how it could have occurred. Even partial eye witness accounts posted here lead to questions. Why was the path of the car so erratic just prior to the accident? Why did it continue to travel so far after striking the cyclist? How did such extreme damage to the vehicle occur? Physical or mental impairment of the driver, some type of sudden medical event, possible intoxication....these are all reasonable speculations that were made by posters here.
I would take them as attempts at understanding rather than as harsh judgements or blame placing. Most commenters here are kind hearted and have offered prayers for both of the injured and their families. As do I.
That being said, just as persons susceptible to certain sudden heart arrythmias, or persons with certain seizure disorders may have their driving privileges restricted, perhaps very, very brittle diabetics should consider this as well. No matter how wonderful a person they might be.
