The truck driver slightly swerves to his left at the last second and leaves dark skid marks at the spot where the cyclist was first seen. There is a big dark round imprint left on the road and the same around the new position, and which both gradually fade away after a few seconds.
The truck driver looks at the dark ring closest to him in confusion as it dissolves. It seems that he doesn't know if he should apologise to the cyclist because he's not sure if it's who he had almost run over. He wanders around dazed while the cyclist heads to sit on the curb. It is clear that he is totally bewildered and trying to figure out how he survived and ended up safely behind in another location with a stranger in a hoodie by his side.
Also notice that the stranger's hands are glowing so he puts them in his pockets when he walks quickly away.
Keep in mind that Angels are "just" another off-world race that use technology to assist them in their work. They have access to hundreds of contraptions that deliver a range of results.
Although many (not all) have wings, they are also assisted by technology so they don't need to entirely rely on their wings for flight.
Everything that appears supernatural or magical about Angels can be understood in terms of their biology and their technology.
