Does electric wire to meter need to be in conduit?
Get something installed to protect these conductors, before your car becomes permanently attached to your electrical service!

Considering that I spy an exposed SE cable below the meter pan, well in harm's way from errant cars and with only the utility's fuses protecting it from faults, I'd flag this installation as a violation of 338.12(A) point 1:


  338.12 Uses Not Permitted.
  
  (A) Service-Entrance Cable. Service-entrance cable (SE)
  shall not be used under the following conditions or in the
  following locations:
  
  (1) Where subject to physical damage unless protected in
  accordance with 230.50(B)
  
  (2) Underground with or without a raceway
  
  (3) For exterior branch circuits and feeder wiring unless
  the installation complies with the provisions of Part I of
  Article 225 and is supported in accordance with 334.30
  or is used as messenger-supported wiring as permitted
  in Part II of Article 396


and 230.50(B)(1):


  (B) All Other Service-Entrance Conductors. All other
  service-entrance conductors, other than underground service entrance conductors, shall be protected against physical damage as specified in 230.50(B)(1) or (B)(2).
  
  (1) Service-Entrance Cables. Service-entrance cables,
  where subject to physical damage, shall be protected by any
  of the following:
  
  (1) Rigid metal conduit (RMC)
  
  (2) Intermediate metal conduit (IMC)
  
  (3) Schedule 80 PVC conduit
  
  (4) Electrical metallic tubing (EMT)
  
  (5) Reinforced thermosetting resin conduit (RTRC)
  
  (6) Other approved means


So, you'll either need to have this service-entrance re-run with a conduit, or see if you can get your local electrical inspectors to sign off on using bollards (i.e. concrete-filled metal poles) to protect the meter pan and service cabling as Machavity suggests.  Or you could do both, if you feel like taking a belt-and-suspenders approach to keeping your electric meter from being a hit-and-run victim.
