Really, though, you should familiarize yourself with MIJI rules. You can just steal his drone like that, or crap up his channels and give him murderous TN mali.
Not unless he forgot Encryption, you can't. Broadcast Encryption so outclasses Decryption as to reduce the MIJI rules to the J rules in most cases (since you don't need to decrypt to jam).
As for the original question, consider that your reading would require that vehicles suddenly reject their armor when they have remote-control interfaces installed. The "(vehicle)" qualification does not draw a distinction with drones (there is no such hard distinction—a drone is a vehicle with a remote-control interface), but rather indicates that it's Vehicle Armor (hardened, etc.) in contrast to Armor (Personal) which provides ordinary Ballistic Armor.
Vehicles of normally-encountered sizes definitely do suffer from a big "feast or famine" effect, where most attacks that have any chance of damaging a vehicle are likely to destroy it with little to no chance of resisting (high-effective-value hardened armor, low Body, AV rounds effectively quarter armor). In our games it hasn't been so much of a problem because we're very risk-averse, so ground drones are rare (on account of the risk of them getting trapped somewhere). Note that the Ferret is quite slow and has an extremely poor Acceleration (which can be covered by a good Rigger, but then the Rigger has to be jumped in and still will probably take several turns to hit top speed. It's also wheeled, which means the opposition can go for mobility kills by shooting out the tires.
With base rules, I've found that the best way to address this is to emphasize the barriers to drone mobility—once the fight gets outside into the clear, the Rigger can dominate the opposition, but while indoors either the team needs to take time and effort to keep the Drone along or the Rigger needs to switch down to more maneuverable, less combat-heavy Drones. It's not ideal, and one of things on the agenda for SR3R is to make more detailed rules for Drone/Vehicle subsystem damage and Mobility Kill/Firepower Kill/Mission Kill rules so that Vehicles can be damaged in important but not catastrophic ways, but that's still a long way down the road.
