Jeffrey Michael "Jeff" Gordon will be 44 years old on August 4.

(FOX) – The four-time NASCAR champ announced today that 2015 will be his
last season as a full-time driver. In fact, it could be the last year he drives at
all, but he’s not ready to say he’ll never race again,

Gordon said "[There’s] always the possibility I’ll compete in selected events,
although I currently have no plans to do that”. 

The 43-year-old won four races in 2014 and finished the season in sixth
place. Teammates and competitors took to Twitter to voice their respect
for Gordon.

The Ford Model T No. 2 was the first vehicle to cross the finish line

car to arrive in Seattle, Washington and ultimately win the race.

On June 23, 1909, a Ford automobile arrived in Seattle from New York City in
23 days flat, completing one of the very early transcontinental automobile races
across North America. This Model T Ford arrives first but is later disqualified
because the drivers changed the axle during the race. The winner, the second
to arrive, is a Shawmut. The race was part of the Alaska-Yukon-Pacific Exposition
(A-Y-P).

Initially as many as 35 autos were entered in the race, but when it started in New
York City on June 1, 1909, at 3:00 p.m., the exact moment that President Taft
officially opened the race, only six vehicles crossed the start line. They were an
Itala, Shawmut, Acme, Stearns, and two Model T Fords.

With the speeds of the cars in those days, it took approximately seven hours 
for that first Indianapolis 500-Mile Race. There were a total of 46 entries and
80,000 spectators in attendance.
