This is wrong, because Car does not have a function called getTotalDistance. 
In the view class do:

class View:

  def getTotalDistance(self):
    total = interfaces.IDistanceTotal(self.context)
    return total.getTotalDistance()

In the view do:

  <div tal:content="view/getTotalDistance" />

Note that you should never ever put a python call into your template.
