Three recent high school graduates were killed and another was seriously injured when a speeding Tesla Cybertruck crashed and burst into flames in California. The four friends were driving the futuristic-looking electric vehicle home from an event in Piedmont just after 3 a.m. Wednesday when it “jumped the curb, struck a cement wall, and then wedged in between the wall and a tree,” police told KGO News. Someone driving behind them from the same event saw the crashed truck and managed to pull one of the passengers to safety, cops told the outlet.
