This is meant to be a lighthearted advert which shows how the VW Beetle helps inject a laid-back, easy way of life into the most serious and boring situations. Having white men talk with a Jamaican accent could be seen as racist by some, but we think it works - and so do most of those who left a comment under the YouTube vid.
It's right at the end of the advert, when a whiny, mid-American voice bleats, "That's the power of German engineering," that things take a turn for the weird.
