A Back to the Future fan has been given a dream speeding ticket - after being caught driving at 88 mph in his DeLorean.
Spencer White was driving down Los Angeles' Highway 14 on Friday (local time) with his mother when she had an idea.
"My mom, she's looking at me and she just says, 'Take it up to 88, let's do it'," Mr White told CNN affiliate KTLA.
"I was at 88 for about two seconds - and, immediately I saw a police officer behind me."
The speed needed to time travel is 88 mph, but unfortunately Mr White was unable to escape back to the future.
Instead, he received a US$400 fine (NZ$560), and was allowed to take a photo of the speed on the radar gun.
Mr White says the reason he couldn't break the space-time continuum was a lack of plutonium for his flux capacitor.
