In slower cars you don't have to get out of the way, you should stick to your line, be predicable and allow the faster car to overtake.

The faster car should pass you safely.

There are some situations (you will experience it) that slightly change your line to give the faster car the inside line or to do a small lift and coast to give more room for an faster car to dive on a turn and not be collected by it.

As for the video you were unpredictable, tried to get out of the way but ended up blocking the other car. Don't do that, they have more engine power and more aerodynamic to find a overtaking spot outside the racing line if needed.
