Just wanted to let you know that you can, in fact, drive a slider manually, too. (Maybe that's common knowledge, but back in the day I was really excited to find it out.)

Access your Sneak, go to the green button on the very left, then don't choose a direct destination but instead just press the button above the destinations: "Calling the Slider". That way you can enter it without being transported somewhere right away. As soon as you enter the Slider, you get this screen:

Now you can choose "Manual" in the top right hand corner.

Even if driving feels strange (it's as if all the vehicles are made out of plastic bubbles or something, avoiding any kind of collision), it is a nice thing to do. And it shows that QuanticDream did try to put lots of neat gameplay-possibilities in the game.

Yeah I was really pumped when I accidentally discovered this back in the day, but my excitement didn't last long. The execution is really poor, the handling is terrible and you bounce off of other sliders and peds, but hey, Quantic Dream was cool enough to add a manual driving mode.

Wish we could drive those bike-sliders like in the intro movie. :)

Yeah, that would have been so awesome!!
