Rate the following essay on its writing, argument, and language skills:
Although self-driving cars are quite an interesting topic, they can be quite dangerous. Throughout the modern age cars have been a major form of transportation and have been constantly modified to match our ever growing needs. But this type of modification can prove to test the limits of safety these machines can offer.

Safety is the key aspect in designing machines for transportation. Be it thicker frames to stronger more durable material. But with giving these machines nearly total control can leave quite the room for worry of failure. The article even says itself that the machines would have quite the trouble traversing "...through workzones and around accidents." That flaw was able to be botched up with the feature to notify the user that human skills are required.

Even if the safety is solved with notifications such as "flashing lights on the windshield" or "seats that vibrate" The cost to build/purchase such technology is still quite absurd. The technology that goes into the ones we have today, namely Google's cars, they would require a multitude of sensors from "positioning-estimating" to a "rotating sensor on the roof" and Google has went to the extremes as to add a "LIDAR, it uses laser beams to form a constantly updating 3-D model of the car's surroundings." So the price continues to rapidly climb as the other devices come into light.

If the the already mentioned safety features weren't bad enough the psychological ones it would create make it even worse than the price. as the article states "Why would anyone want a driverless car that still needs a driver? Wouldn't drivers get bored waiting for their turn to drive?" And that is entirely true because you would have to be constantly alert in case the car comes across trouble and needs your assistance. They plan to battle this with "in-car entertainment" but it would still be quite bothersome to be constantly vigilant for imminent danger. And yes the laws would adapt but it is currently, and logically should remain, that a "safe car has a human driver in control at all times."

With the issues in safety, price, and psychological area's of this proposal it will clearly take more than a few half-baked solutions to fix these bothersome quirks. It is clearly too much of a hill to climb for our current technology and budget to attempt until a later date. But the proposal is still a daring and appealing one on the surface and should be kept close for the time that we are feasibly able to carry it out.
