Hey there!

Yes, it's difficult to maintain a constant speed of a vehicle.

Step-by-step explanation:

Because, roads surfaces are not always smooth, they are rough too, for which friction occurs.

Hope it help you

Answer:

The road surface is always rough, so the frictional force between the tires and the road surface make it difficult to maintain constant speed because acceleration always changes.
