Sincerest condolences to the family for their tragic loss.
We may never know what actually happened, but anytime a
2010 Prius is involved, the media, and police, both need to
be made aware of its astronomical number of
brake system complaints, among all the others too.
The 2010 Toyota Prius has an ASTRONOMICAL NUMBER
OF BRAKE FAILURE COMPLAINTS (and should have been
RECALLED years ago, to fix ALL OF THE FAILURE MODES);
not to mention “the admitted” software-based brake failure
issue, among all the other brake failure modes, as filed in
numerous brake system complaints to NHTSA, by
2010 Toyota Prius owners.

A father and son were killed in a crash Thursday near Groveland in Lake County, according to the Florida Highway Patrol.
Michael Reese Sr., 65, and Michael Reese Jr., 40, were from Center Hill, FHP Sgt. Kim Montes said. They were driving east on Austin Merritt Road shortly before 11:30 a.m., and Jose Zambrano, 32, of Santa Ana, Calif., was driving a semi-truck northbound on County Road 33.
Reese Sr., who was driving, tried to turn left on CR 33 but pulled into Zambrano’s path, Montes said. The semi struck the right side of their 2010 Toyota Prius.
The crash remains under investigation.

Toyota: Software to blame for Prius brake

Toyota officials described the problem as a "disconnect" in the
vehicle's complex anti-lock brake system (ABS) that causes less
than a one-second lag. With the delay, a vehicle going 60 mph will have traveled nearly another 90 feet before the brakes begin to take hold.
