As someone who's personally experienced driving along at 70mph before hearing the most enormous bang,
feeling the car veer sharply out to one side and watching smoke and fragments of tire fly off back down the motorway from a sudden sidewall blowout, I can confirm you don't want to experience it.
New this year is Lane Keep Assist, but I never
felt the
car steer itself back into the correct lane, despite my purposely
veering off course to test the system.
