from datetime import datetime
from random import randint
import matplotlib.pyplot as plt
import pandas as pd

# Constants
VEHICLE_TYPES = ['Car', 'Bus', 'Truck', 'Bike']
OUTPUT_DIR = './output'


def task_func(hours, output_dir=OUTPUT_DIR):
    """
    Generates traffic data for different vehicle types over a specified number of hours,
    saves the data to a CSV file with coloumns 'Time', 'Car', 'Bus', 'Truck', and 'Bike',
    and plots the data in a line chart with 'Time' on x-axis and 'Vehicle Count' on y-axis.

    Parameters:
    - hours (int): Number of hours to generate data for.
    - output_dir (str, optional): The output file path

    Returns:
    - tuple: Path to the CSV file and the matplotlib axes object of the line plot.

    Requirements:
    - pandas
    - os
    - csv
    - matplotlib.pyplot
    - random
    - datetime

    Example:
    >>> import matplotlib
    >>> file_path, ax = task_func(2)  # Generate data for 2 hours
    >>> isinstance(file_path, str)
    True
    >>> 'traffic_data.csv' in file_path
    True
    >>> isinstance(ax, matplotlib.axes.Axes)
    True

instruct prompt

Generates traffic data for different vehicle types over a specified number of hours, saves the data to a CSV file with coloumns 'Time', 'Car', 'Bus', 'Truck', and 'Bike', and plots the data in a line chart with 'Time' on x-axis and 'Vehicle Count' on y-axis.
The function should output with:
    tuple: Path to the CSV file and the matplotlib axes object of the line plot.
You should write self-contained code starting with:

Code

import csv
import os
from datetime import datetime
from random import randint
import matplotlib.pyplot as plt
import pandas as pd
# Constants
VEHICLE_TYPES = ['Car', 'Bus', 'Truck', 'Bike']
OUTPUT_DIR = './output'
def task_func(hours, output_dir=OUTPUT_DIR):
