Accelerating escalators are both fascinating and absolutely terrifying to me.

[a-priori]

I've walked on the ones at Toronto Pearson before. I was a bit surprised the first time that it wasn't moving at full speed like I expected when I stepped on, but after that the second time I knew what to expect and it worked well.

I actually found it better when disembarking because it gives a better transition to the stationary surface when stepping off.
