"The moments before and after everything changed for Tiger Woods"

As word of a “black box” subpoena from investigators surfaced in Tiger Woods’ single car accident, ESPN.com’s Bob Harig and Ramona Shelbourne have pieced together the days before and since in what is the most definitive account should you be up for reliving what could be a career-ending wreck.

Harig notes these questions remain.

According to doctors familiar with the back procedure Woods had, it is normal to be cleared to drive within several weeks of surgery if an individual's pain tolerance allows. Which meant it was up to Woods, and he likes to drive himself. He has almost always shown up for tournament rounds with his caddie Joe LaCava, or Steve Williams before that, or with friend Rob McNamara in the passenger seat. He has even been known to make the four-plus-hour drive from his home in Jupiter to the Players Championship in Ponte Vedra Beach, Florida, with people recognizing him along I-95 or at a gas station.

Woods had driven himself to Riviera on Saturday and Sunday. He'd driven himself to the set on Monday, filming various outtakes and scenes for Discovery-owned GolfTV. And he was familiar with the area from previous trips.

While locals who live near the crash site initially speculated Woods could have been surprised by the steepness of the grade going north on Hawthorne Boulevard, that does not appear to be the case.

The LA Times’ Meg James and Wendy Lee previous looked into the question of why he was driving at all for what was an extensive two-day shoot by Woods standards.
