Error, but can't find the bug

I am doing task 2.

I have read the instructions multiple times but I can't find what I'm doing wrong

racecar.py 
class RaceCar:

    color = None
    fuel_remaining = None
    laps = 0

    def __init__(self, color, fuel_remaining, **kwargs):
        # setattr(self, "color", color)
        # setattr(self, "fuel_remaining")
        self.color = color
        self.fuel_remaining = fuel_remaining

        for key, value in kwargs.items():
            setattr(self, key, value)

    def run_lap(self, length):
        self.fuel_remaining = self.fuel_remaining - length * 0.125
        laps += 1

You just need to do self.laps += 1 instead of laps += 1, otherwise it wouldn't reference the instance.

class RaceCar:

    def __init__(self, color, fuel_remaining, **kwargs):
        self.color = color
        self.fuel_remaining = fuel_remaining
        self.laps = 0

        for key, value in kwargs.items():
            setattr(self, key, value)

    def run_lap(self, length):
        self.fuel_remaining -= (length * 0.125)
        #This is the change
        self.laps += 1
