Some info might be gleaned from the pinned speedometer reading but it'll be difficult to infer the speed of the vehicle when it left the road.

Baarts said the speedometer in the car was "pinned" at 90 mph when they recovered it at the bottom of the cliff near Mendocino, California.

"The most-likely cause for that reading is the shock from the impact," Baarts said. "So whenever a vehicle slams into something it's fairly common the speedometer will lock at a certain speed. But you cannot use that information [except] for a base, just for the speed of the vehicle. There are several other factors that need to be considered."

From the GPS of the turnout, 39.694752, -123.798602 the water is 60m West North West of the turn out (assuming a North bound trajectory) and 40m South South West of the turn out (South bound trajectory).

At 145 km/hr, neglecting wind drag, the SUV would have sailed 100 m before it dropped to sea level assuming the turn out is 30m above sea level.

It would have landed well out in the water if it was going 40m/sec but the photo shows that it didn't quite make it to the water.

This doesn't prove the driver wasn't suicidal, just that very little information can be gleaned from the 90 mph "pinned speedometer" reading.
