Car editor Niek Schenk answers: ‘Traffic information is mainly intended to indicate the delay. This used to be done exclusively in kilometres, nowadays increasingly also in minutes. You’re right: if you put all those cars in a row on a four-lane highway, the traffic jam would actually be even longer. But it doesn’t matter for the delay, as long as the cars in all four lanes are traveling at about the same speed.’
