More recently, however, General Motors made a self-driving car in 1958 that adjusted its steering wheel based on the alternating currents given off by a wire placed inside the road. While the vehicle did actually drive itself, it does not qualify as the first autonomous vehicle because it depended on wires placed inside the ground. The world's first autonomous vehicle was made by S. Tsugawa and several of his colleagues at Japan's Tsukuba Mechanical Engineering Laboratory. However, German engineer Ernst Dickinson is regarded as the pioneer of the autonomous car. In 1987, he developed the VaMoRs which was capable of traveling more than 90 kilometers per hour (55 mph) for about 20 kilometers (12 mi). Seven years later, he made the VaMP, which could recognize road signs, know its own position in a lane, detect other vehicles, and even decide when to change lanes. And a year after that, he and his team made another autonomous vehicle which traveled from Germany to Denmark. The vehicle had a maximum speed of 180 kilometers per hour (111 mph) and was controlled by a human for about 5 percent of the journey.

Don't worry. Many women don't feel anything yet this week. In fact, most early pregnancy symptoms don't start until about 6 weeks.
Tender, swollen breasts
Breast tenderness can be one of the earliest signs of pregnancy. It usually starts around 4 to 6 weeks and lasts through the first trimester.
For many women, exhaustion is one of the first signs of pregnancy. But other women hardly seem to slow down at all.
Nausea or vomiting
Morning sickness can strike at any time of day. It usually starts around 6 weeks of pregnancy but can begin as early as 4 weeks. Some women have cramping as well.
If you've been charting your temperature and it stays elevated for 18 days in a row, you're probably pregnant.
Take a pregnancy test
If you haven't already, you should be able to find out whether you're pregnant. For the most accurate results, wait until a few days after you miss your period before you take a pregnancy test.
Make a prenatal appointment
If the test is positive, call your doctor or midwife and schedule your first prenatal appointment. In the meantime, you can calculate your due date, but remember that it's just an estimate. You're just as likely to go into labor any day during the two weeks before or after.
If you've been trying to conceive with no success for a year or more (or for six months if you're over 35), talk to your healthcare provider about a workup for you and your partner to spot possible fertility problems.
