A Gateshead plumber saw his job fall into the water after he was caught driving under the influence to escape a samurai swordsman.
Ethan Rae, 20, was fleeing a party when a guy brandished a knife and feared he would be pressured to use drugs.
But the poor condition of the wheels of his Seat Ibiza – and the erratic driving – were spotted by police when he drove home at 11.15pm on Monday 12 April.

They stopped him on the A183 at Shiney Row, near Sunderland – and a roadside breath test came back positive, a court heard.
Rae, of Sea View, Felling, Gateshead, is facing a 14-month driving ban after pleading guilty to driving with too much alcohol.
His lawyer told South Tyneside Magistrates’ Court that it was likely that Rae’s conviction would cost him his job.
Prosecutor Glenda Beck said: “An officer saw that the defendant’s two offside tires were both so punctured that they were on their rims.
“The officer negotiated behind the Seat and became aware that the vehicle was driving erratically. He instructed the vehicle to stop.
“The suspect told the officer that he had been drinking before. He seemed dazed and confused.”
Ms Beck said a roadside breath test showed 47 mcg of alcohol in 100 ml of breath. The legal limit is 35mcgs.
But the level had risen to 51mcgs by the time of a subsequent weight of evidence test at the police station, she confirmed.
Angus Westgarth, defensively, said: “He had taken people he knew loosely to a party. He would leave his car.
“Drugs were being pushed around and someone he didn’t know was waving a samurai sword around.
“He thought he would be pressured to do drugs and decided to take his car home.
“He’s a plumber by trade. He understands that his job will disappear immediately.
“With the disqualification he will probably lose his job, it will have a dramatic effect on him. It is a wholesome experience.”
Deputy District Judge Mark Daley banned him from driving and told Rae, “As you know, the law is very strict in this area.”
Judge Daley also fined him £275 with £85 court costs and a victim allowance of £34.
