Drive by has been impressing me lately, this is a very powerful and versatile card. It serves several real needs for the criminal runner.
First and most obviously, It gets the runner out of the Mushin No Shin trap. Even in the endgame, when the runner's rig is powerful enough to get in everywhere the Corp can still try and turn the tide with ambushes. IAA behind ice, and the runner has to ask himself, is that really an agenda, or is it an ambush? Many corp come from behinds have come about because the runner has paid through the nose to break ice and stepped right into an Aggressive Secretary or Project Junebug. Spending the first 2 clicks on a Drive By ensures that you only go if the card in question is actually a agenda, and warns you of anything specific about the Agenda you need to fix to steal it. (NAPD Contract etc.)
Even if the corp isn't running ambushes, the Drive By can make its slots back by smashing upgrades. When the corp IAA's a card in a server with an agenda, the runner must ask themselves if that is Caprice Nisei or Ash 2X3ZB9CY, or even Marcus Batty. Any of these can make the run into a misery. But with a drive by, all of a sudden you just have to fight the ice to make the steal.
If the corp isn't doing ambushes or upgrades, perhaps they are using an asset based economy? It is important to remember that the trashing effect of Drive By happens with no cost. The corp usually waits till the appropriate time to rez their assets. Preempt that with a Drive By and you can save yourself a lot of money on that SanSan City Grid or other expensive to trash asset.
Obviously, the Corp can render 2 and 3 less viable by rezzing their assets or upgrades immediately, but the runner is not unhappy if they go down that route. Knowing exactly what's out there is an advantage that it is tough to put a price on, and since the corp is spending money to rez these assets/upgrades, they will be less able to rez their ice.
This is a card that competes strongly with the other fantastic criminal run events. Many decks will benefit from including Drive By.
