The cyber truck is more bulletproof than any normal car, there are tons of videos of it stopping handgun rounds.
For what it’s worth, my $600 hunting rifle will go clean through both sides of any bulletproof vest, and it’s nothing special.
For everything that is bulletproof, there is always a calibre of projectile that will go through it.
Your hunting rifle will also go through a cybertruck. Its side panels are proven on video to stop fat and slow handgun rounds like .45 ACP. I would bet pretty good money that if I took a 1911 chambered in .45 ACP and shot the doors of a 1970s steel monstrosity of a passenger sedan it would also dent and not penetrate the doors.
Some old cars bodies probably could stop small pistol rounds too.
