Thanks to MG Brasil!
And the award for most highway that fills the bag goes to the British ... ... ... M6 Motorway! The longest road full of traffic jams and more of England was the choice of most research, this record influenced by the accident and her problems.
The M6, 230 miles long, reaches a peak traffic of 180,000 cars per hour, well above the planned capacity of 72,000!
Other roads were horrible found the A30 ("bottleneck 284 miles of traffic"), and M1 ("200 miles of congestion").
