text: In conclusion, online or video conferencing classes is terrific idea because a student can be sick, allows for students to have more practice, and it allows students to get work done if they don't have a way to school. By allowing online or video conferencing students won't feel left behind when returning to school from an absent. Also by allowing online or video conferencing there would be a spike in test grades because students would extra practice with the teacher.Driverless Cars is a great idea, these cars would make a huge change in the world because these cars would be really helpful, but there are some adventages and disavenges of the use of these cars, one adventages is that can drive by themselves, but a desaventage is that if the sensors don't work what would happen?.
