I loves it on so many levels.
That is definitely rush hour in Houston.
Hot Wheels was my favorite toy as a kid. I remember when I gave my beloved old Hot Wheels to my son. He started to crash them into each other, “Oh no, a car is stalled on the track!!!” My initial reaction was, “Be careful with those beloved antiques!” To my credit, I promptly remembered how Scott and I used to play with them and gleefully joined in on the carnage. 
Me and my little brother ran Hot Wheels track up onto the roof to get a huge slope. Turning the track up at the bottom would launch them 20 feet through the air. If we had a giant slide like that we would have tried it out.
