Feature: Car - Max speed restrictions
When a max speed is set, osrm will use 2/3 of that as the actual speed.

    Background: Use specific speeds
        Given the profile "car"
        Given a grid size of 1000 meters

    Scenario: Car - Respect maxspeeds when lower that way type speed
        Given the node map
            | a | b | c |

        And the ways
            | nodes | highway | maxspeed |
            | ab    | trunk   |          |
            | bc    | trunk   | 60       |

        When I route I should get
            | from | to | route | speed   |
            | a    | b  | ab    | 85 km/h |
            | b    | c  | bc    | 40 km/h |

    Scenario: Car - Do not ignore maxspeed when higher than way speed
        Given the node map
            | a | b | c |

        And the ways
            | nodes | highway     | maxspeed |
            | ab    | residential |          |
            | bc    | residential | 90       |

        When I route I should get
            | from | to | route | speed   |
            | a    | b  | ab    | 25 km/h |
            | b    | c  | bc    | 60 km/h |

    Scenario: Car - Forward/backward maxspeed
        Given a grid size of 100 meters

        Then routability should be
            | highway | maxspeed | maxspeed:forward | maxspeed:backward | forw    | backw   |
            | primary |          |                  |                   | 65 km/h | 65 km/h |
            | primary | 60       |                  |                   | 40 km/h | 40 km/h |
            | primary |          | 60               |                   | 40 km/h | 65 km/h |
            | primary |          |                  | 60                | 65 km/h | 40 km/h |
            | primary | 15       | 60               |                   | 40 km/h | 10 km/h |
            | primary | 15       |                  | 60                | 10 km/h | 40 km/h |
            | primary | 15       | 30               | 60                | 20 km/h | 40 km/h |

    Scenario: Car - Maxspeed should not allow routing on unroutable ways
        Then routability should be
            | highway   | railway | access | maxspeed | maxspeed:forward | maxspeed:backward | bothw |
            | primary   |         |        |          |                  |                   | x     |
            | secondary |         | no     |          |                  |                   |       |
            | secondary |         | no     | 100      |                  |                   |       |
