suicide-ok, single body, nothing in the article to indicate that she was forced off the road by another car. The crime itself, even if guilty? How much actual time in jail? Is this worth suicide? Points against it, except from the good insurance angle presented, but still,it's not "heavy" enough of a crime for that, IMO.
ok-murder then. How the heck was it pulled off? Some mechanical contraption that made the steering go bad the same time as the throttle got applied, the brakes stopped working, and the gear shift wouldn't drop to a lower gear or park? That's pretty complicated. An incapacitating gas released in the back seat with a timer or radio control? Less complicated but still pretty overkill just for drivers licenses. Another, a dazzling laser shown through the windshield or side window at close range, a passing car or well ahead of hers? Powerful enough to blind enough to cause loss of control, at an opportune spot on the road.
I'm just trying to pin down any possible way, given this articles dearth of details, how a murder could have technically been accomplished.
This is too puzzling, occams razor doesn't fit either scenario that well. OK, one more, she was drugged surreptitiously, it started to kick in after she was behind the wheel. Then there's regular old gunshot, too, and it just hasn't come out in the autopsy yet. The other witnesses in the cars might not have heard the shot, that's possible.
Need more data here, but it's not just a coincidence with the crime being uncovered, that's too improbable.
