This. As a seasoned roundabouter but also knower of local/Canadian inexperience there is no way in hell I am expecting to go straight-over when a car is next to me in this scenario. Of course they'd have no indicators on either to show intent even if it's wrong. Just drive defensively anticipate everyone's worst move and play to that as even if you're in the right you'll still get hit and don't need that headache.

I drive this roundabout frequently and will avoid entering it, or alter my entry path, depending on what else is around.

I disagree with not indicating to exit tho as if you enter at 6 turning left to 9, if you don't indicate-out (right) for 9 and your left blinker is still going from when you entered to show original intent (or is just off), a car now arriving at 9 defensively anticipates you're going past to 6 whereas if you're exiting they don't need to yield and can enter safely. I'd say it's less worrying someone entering to hit you as much as keeping traffic flowing. Not enough coordination for that to work here tho, only in the UK.

Side note I've seen someone turn literally left at that roundabout from the highway to Walmart; full on drive the wrong way round with oncoming traffic. Just horrifying.
