6f4pmw | Why in most video games, does it seem that Friendly/Ally A.I. has a much worse A.I. then what Agressive/Enemy A.I. have? | For example; many games have enemies that will only attack the player once they are in sight, but the ally will notice enemies through a wall and will attack the wall thinking they are making progress. | Technology | explainlikeimfive | {

6f6i7e | To what extent would electric cars help in reducing carbon emissions? | If there is a sudden increase in electric cars, the demand for electricity to charge the electric cars will also increase. This would lead to more burning of fossil fuels to produce enough electricity to cope with the rising demand, especially considering that electric cars don't have great mileage.
