Red car as it enters an intersection with traffic circle traffic to the right of the blue car.
Blue car, as it is driving on the road with traffic circle traffic.✓Bonne réponse
Explication
Priority belongs to the blue car because it is already travelling on the circular roadway governed by the roundabout rule. The claim that the entering red car gains precedence from its relative position wrongly substitutes ordinary uncontrolled-junction priority for the rule that protects circulating traffic.
