Question about turning into main road

I have a question about mergin into the main road recently. From the picture, assuming that two cars are merging into the main road (as per picture, two cars are turning from left into the main road). There is no line to split the road on the left into two lanes. Questions are:

  1. Can two cars be side by side on the left road?
  2. After the blue car has merged almost entirely into the main road with the red car still at the left road not yet merged into the main road, does blue car need slow down for red car to enter?

Thanks!
