Amanda Bynes is on a roll when it comes to bad driving. In the last couple of weeks, the 26-year-old Easy A actress deserves an F for her efforts behind the wheel. On April 6, Bynes was busted for driving under the influence. Just a couple of days later, the hard-partying former child star was photographed hopping a parking curb outside a Hollywood hotspot. Continuing her marathon of questionable driving stunts, Bynes was supposedly seen "holding up traffic and doing an incredibly slow... 3-point turn in the middle of Robertston" Sunday night. An onlooker tells People, "It was taking forever and she finally made it into the driveway. She looked wobbly - I guess it could have been the heels since she was wearing sky-high nude pumps, but she did seem out of it." The source adds that Bynes skipped out on paying the valet the $8 charge before going into SUR restaurant and bar. The party apparently never ends for Lohan 2.0 -- Bynes was also spotted at Nylon's Voli vodka-sponsored Coachella party on Saturday night. The Hairspray actress should probably consider a chauffeur before she ends up following in another famous starlet's footsteps.
