Automobile Timeline

• 1911: the electric starter was introduced. I found this interesting because before that the engine was started by hand cranking. 
• 1935: flashing turn signals introduced. I found this interesting because now those are a big part of driving a vehicle. 
• 1939: the first air conditioning system added to automobiles. I found this interesting because the AC is used all the time in cars today, so imagine a hot summer day without it. 
• 1970: airbags become standard. I found this interesting because they are in all cars now.
