AIBU to think this isn't good driving?

Imagine you're turning onto a slip road to join a very busy dual carriageway in rush hour. The slip road is quite short as far as slip roads go and you have to merge on, don't get your own lane as you join.

So, there is a car in front of you and a car behind you all wanting to join the dual carriageway. Who should join first?

I've seen a few near misses. What happens, is that the driver at the front is a bit hesitant, and the car at the back gets impatient waiting in their car (which can get up to 60 in less than 7 seconds) and joins by pulling out and slamming their foot down. My issue with this, is that it takes so little time to pull out and slam your foot down, that you're risking the cars in front crashing into you because their blind spot was clear, but you suddenly pulled out as they looked forward to go, and you are essentially relying on them looking at their blind spot in that split second. Also, with the car at the back going it then means the middle and front car have had the gap they could have used, filled, so they then haven't even got a shot at joining.

I am the middle car in this situation, btw. AIBU thinking it isn't good road sense to do what some cars at the back do?

A lot of this type of drivers fail to realise how much slack the rest of us are cutting them.
Amen to that.
I agree with the OP.

I wish they could make some sort of driving test that weeds these people out.

I used to have a tiny fiat 126 that could only do 62mph. I tended to avoid motorways tbh

By overtaking in that situation your more likely to make the driver unnecessarily hesitant. Not only are they worrying about the gap but the idiot behind who may or may not pull out.

I do think you should have to have motorway lessons though to teach people how to drive on them. It seems bananas you can drive on them with no experience, only dual carriageways.

I've been coming down a slip road and had my view of the dual carriageway totally blocked by a pick-up (Animal/warrior/crusher) moving over to pull out from a 'right up my arse' position, then pulling out behind me/accelerating fast. This left me no option but to slam on the brakes then wait for a big enough gap to accelerate from 0. Had he not blocked my view/pulled out so far I'd have been able to merge at normal speed. Dick.
