LAST EDITED ON 10-06-13 AT 08:46 PM (EST)The taxi thing was dumb, but I can see why it took a little while to realize that the person riding in the taxi was the one actually doing the roadblock. So one person had to both paraglide and row a boat, while the other rode in a taxi and then waited on land. It did seem a little off balance for what normally happens when they are required to switch tasks in roadblocks.
