The marginal risk of spike strips relative to the cost of installing and maintaining run-flat tires is minimal compared to the marginal risk of a radio transmitting (likely with GPS) transceiver that can locate and disable a car relative to the cost of disabling, removing, or spoofing said transceiver. For a longer explanation, spike strips require multiple layers of failure in any criminal activity before they become a concern. You have to be in a car, have alerted police, have not been a good enough driver to elude police, and driven in a consistent direction long enough that they can predict where you'll go and drop spikes. If you're not performing a minor infraction, or you're a criminal who plans ahead, the probability of all these things happening, and you not being able to do anything about any of them is minimal. If you have a radio transmitting GPS on your car that can disable it you only have to hit the first step - be in a car. You don't even have to have police on alert. You can commit a crime, have gotten away, be driving around the next day, and as they're reviewing tape, they'll note your car, see the license (or ID the make, model, markings, and driver), find you, and then disable you wherever you are. All criminals will remove this as a matter of course. This doesn't even speak to the pattern recognition and behavioural attacks that this would allow on any criminal organization, enabling things like predictive surveillance (there's a big car pow-wow on 5th and Lake St. every Sat. night), optimal raids (same), or covertly nabbing members (Dino likes to go for a snack at 8:00 every night). Further, this is easily as bad as the NSA "meta-data" scandal, since the pattern recognition above used against all common citizens is absolutely begging for abuse by middle managers and line-workers (where's my girlfriend going?)
