Interesting. And now I've checked the arrow markings at the 'turbo-ish' Ovangle Road roundabout here in Lancaster at the A589/B5273 and that has got inconsistent arrows on it to send the unwary into the wrong lane.
4:06 building on what you said i don't like that we re engineer things that work and break them to the point that they are entirely different or just don't work, look at the junction in the M25 with the A3 and black cat roundabout, which shows that roundabouts are largely unfit for purpose nowadays
God, did KCC really call that paint outside Ashford a turbo roundabout? It's just a normal roundabout with some red bits, and have you seen the awful unauthorised signs? I've driven it a few times and for me I couldn't see anything really different for safety or traffic speeds. Same with this bit of paint, albeit slightly better. Too many different markings, chevrons and red painted areas when simple dashed lines and kerbs between lanes would do the job better, like a normal roundabout.
British roundabouts often seem quite inefficient to me, IMHO. Wide expanses of tarmac with poor or no lane markings + geometries which cause speeds to be so high that it can't be good for capacity or safety.
I can already see the confusion those road markings could cause. Coming from the bottom of the diagram, in the left lane it seems you can go left or ahead, yet you cannot take the third exit from the left lane, which sure it is slightly past 12 o clock but many drivers may think that they can access it from the left lane.
At least these roundabouts have road markings – here in Surrey, there seems to be an aversion to repainting road markings so that on some roundabouts (looking at you junction 8 on the m25 (Reigate Hill)) there’s barely any indication of lanes or symbols on the tarmac!
There are 5 arms on the roundabout but only 4 on the road markings, and it's inconsistent what they indicate. For instance, coming from the right, exit 3 is deemed "straight on", but coming from the bottom it's exit 2.
I don’t understand why would you want to make a normal roundabout a “turbo roundabout”. Most roundabouts that were built are designed in such different ways and making that roundabout would confuse a lot of drivers. Just like the Magic Roundabout in Swindon, Wiltshire.

Gotta love label things that clearly aren't what the name says it is

Bryn,
CalTrans recently put in a "turbo roundabout' at a dangeroeus intersection near Hollister, CA; (Local news video on it: https://www.youtube.com/watch?v=1yK84IHXm-M)

Very interesting video, and yeah, this is clearly not a turbo-roundabout.
Interestingly, I found out Estonia had some as I was exploring Estonian roads for my vacation there, where I'll rent a car for one day.

Of course it wouldn't be Britain without a new type of roundabout. 😂 How many different roundabout types are there?
Wouldn't they need to train Audi drivers to understand lanes and road markings first? 😁
Interesting video, young Bryn. Well done mate.
What's the name of the type if roundabout at Fiveways Island in Birmingham?
Its adds lanes and loses lanes as you go around, and sends you to the correct exit, so you don't need to change lanes.
Check it out on Google Maps 👍

I drive on this roundabout every day. They have just started work on the changes. Going to be interesting.
