Will we have cars in the future? Yes,I think we will,but they'll be very different from today's cars.First,they won't use petrol or diesel, brcause we won't have enough oil in fifty years'time.Cars will probably use electricity or hydrogen.So they'll be quieter and cleaner.And i think the roads will be safer,too,because you won't actually drive your car.You'll just sit in it and the car's computer will drive it.So there won't be any accidents.
