Yes, it just depends on how you define which way is "positive". If you define the "backwards" direction to be the positive direction, acceleration will be positive when going "backwards". Note that if we define the axes like this, going "forwards" will give the car a negative acceleration.
For a car's speed to increase and have a positive acceleration, the car's velocity needs to be increasing in the same direction as its acceleration. This means that the car is speeding up. When the velocity and acceleration have the same sign (both positive or both negative), the car's speed will increase.
The car is slowing down
No, if a car is slowing down, its acceleration is negative. Acceleration is defined as the rate of change of velocity, so if the car's velocity is decreasing, its acceleration is in the opposite direction.
positive acceleration helps to increase the velocity for positive direction while negative acceleration resists the motion.

No, driving backwards does not add mileage to a car. Mileage is calculated based on the distance traveled in the forward direction. Driving backwards does not affect the odometer reading or the overall mileage of the vehicle.
No, driving a car backwards does not affect the mileage in reverse. The odometer measures the distance the car has traveled regardless of the direction it is moving.

driving a car into a wall
Yes.If the car is backing up, but slowing down, then its velocity is in the negative direction, and its acceleration is in the positive direction.
The car is slowing down
The velocity of a car traveling backwards would be negative, as it is moving in the opposite direction of its positive reference point.
the car is weak
The acceleration of the car is equal to the rate of change of its speed over time. When a car goes from zero speed to a higher speed, it experiences positive acceleration in the direction of its motion.
