Multiple times TAR producers/editors decided not to show the roadblock in the leg, even though it occurred, as they wanted to accent more drama around flights or whatever.
In TAR5, in Dubai and in the final leg in Alberta the roadblocks occurred but were not shown. The Dubai roadblock was skipped to watch Colin make a total ass of himself in Tanzania. In fact, the missing roadblock in Alberta had private photos which provided major spoilers for that season.
I couldn't figure out exactly where the missing roadblock may have occurred. Anyone else?
