Jacobs clearly has a need ... a need for speed. (Getty Images)

49ers running back Brandon Jacobs is obviously a fan of speedy driving. Even during those times of his Giants career that he has been depressed or mad, when he’s not getting enough carries or not getting the money he wants, he always could fall back on his “fast-ass” cars for entertainment and enjoyment. That usually seemed to put a smile on his face.

Now, though, it looks like Jacobs’ need for speed might get some New Jersey state troopers in trouble.

According to the Newark Star Ledger, the state police are investigating the possibility that two troopers were part of a “caravan of luxury sports cars at speeds in excess of 100 mph down the Garden State Parkway to Atlantic City last month,” including a vehicle driven by Jacobs.

The Associated Press reports that New Jersey Governor Chris Christie called the high-speed caravan a "dumb thing to do."

Apparently, those two troopers, with lights flashing, were driving in front of and behind the caravan, basically giving the cars a police escort. The vehicles included Porsches, Ferraris, Lamborghinis, among other expensive cars, and they had their license plates covered with tape.

"I had the great pleasure today of nearly being killed by, not one, but two, Lamborghinis traveling in excess of 110 mph in a (New Jersey State Police) escorted ‘caravan’ of approximately 30 exotic vehicles all traveling well over 100 mph," citizen Wayne Gantt wrote to the New Jersey Turnpike Authority, via the Star Ledger.

When contacted by the paper, Jacobs’ agent, Justin Schulman, said, “Brandon was part of a group that went down to Atlantic City on March 30."

Another citizen wrote in a complaint, “When I was in the high speed lane passing a series of slower vehicles, I saw police flashers in my rear view mirror, moving at a high rate towards me, so I sped up, passed the cars and got into the slower lane in the nick of time.

"The car raced by me going (estimated) 100+ mph. Then I noticed there was a series of performance cars (Porsches, Ferraris, etc.) that were following the lead police car with their blinkers on and license plates taped off -- speeding at the same high rate. I noticed that many cars were struggling to get out of their way safely."

After the Giants released him last month, Jacobs signed a one-year deal with San Francisco. Here's hoping nobody points him toward Lombard Street.
