"Riders understand that is a big attraction and the majority of time it is OK. The risks might not be as bad as television makes out because there are generally police motorbikes in front of the riders.
"I think it was more of an issue in the UK because the public are not as accustomed to road racing and they got a bit over-excited compared to continental Europeans. Ninety per cent of people move out of the way at the right time and others follow suit."
Australian-owned Orica-GreenEdge sat 18th of 22 teams going into stage 13. Dean said they'd failed to achieve some of their targets in the early UK stages but had some remaining ambitions.
"We're not a big team with a 'general classification' riding budget but I'm sure we can pull off a stage win before it finishes. One aim will be [Sunday's 222km flat] stage into Nimes which can be particularly windy. Our guys are good in that sort of stuff. We'll also be gunning for the individual time trial on the second-to-last day."
Dean rates Astana's Vincenzo Nibali the strongest prospect to take overall general classification honours, especially after Team Sky's Richie Porte dropped out of contention.
"Nibali has looked good from the outset, especially on the cobblestones, and he's previously won the tours of Spain and Italy. He knows the business and has a good team around him."
