Reportedly the driver of the Mercedes got out of his vehicle after the crash, walked over to a sofa in the lobby, sat down, then said nothing.
Doesn’t sound like a medical event.
I read that the driver is a female. It sounds like a mental illness event. TDS is a big problem when sufferers get into position to operate deadly weapons like cars. There should be Red Flag laws designed to deny driving privileges to those known to be afflicted with TDS. Heck, it could even be personalized with a name like “Emily’s Law” or “Barkevious’ Law”. Just call if “Covfefe’s Law”.
