'follow-me' cars, and progressive taxi can be used, but at a towered airport, ground control will give you that with your taxi clearance.
"United 2133, Laguardia Ground, taxi from the commercial ramp to runway four using taxiway alpha, echo, and bravo."
Using a taxiway diagram from the A/FD, you would locate your position on the plate, the taxiways in question and from there determine the route you will take. In this case you'll turn left from the ramp heading northwest on taxiway A, then take a right on taxiway E, then take a left on taxiway B.
If you are unfamiliar with the airport, you can then request a progressive taxi."
"LaGuardia Ground, Beech 2375 X-Ray, Unfamiliar with the airport layout. Request progressive taxi."
NOTE: This will annoy controllers at busy airports if you habitually do this as it is expected that you have this information ready at hand before you call ground requesting a taxi clearance.
The 'follow me' vehicles are usually used for quickly routing VIP or special use aircraft to a section of the ramp e.g. Trump's 757 to a section of the ramp cordoned off for a campaign rally, etc.
