text: Another reason why smart cars would not be a good developement would be the cost of the car. The car may be very high at price and wouldnt sell. It could also get a huge donation to get the car started but that money could be a waste by not having a successful project. The car could need something new and it could turn out to be very expensive and won't get fixed being left alone. The car may also need a special street to give it eletrical signal which would be expensive to remake new streets. Smart cars may just be a waste of money.
