根据我查到的资料，他说的应该不是真的。针对不系安全带的锁定措施可能是有的，例如限制车速。但没有证据表明不系安全带会影响任何安全机制的激活。

A 2012 highway reauthorization law relaxed these restrictions. Now NHTSA can permit automakers to equip vehicles with belt interlocks as an alternative means to comply with a federal safety standard.

In the IIHS study involving part-time belt users, a speed-limiting interlock that held the vehicle speed to 15 mph during unbelted driving was just as effective as the persistent reminders, increasing belt use by 33 percent (Kidd & Singer, 2019). A gearshift interlock increased belt use by 16 percent, though the change wasn't statistically significant.

The study found that drivers were easily able to circumvent the interlocks — for example, by sitting on the belt or buckling it behind their back. In addition, some participants raised safety concerns about limiting vehicle function or being unable to drive the vehicle in an emergency.

A national telephone survey found that 70 percent of part-time belt users and 44 percent of non-users said they would be more likely to buckle up with ignition interlocks. However, only 30 percent of part-time belt users and 16 percent of non-users thought ignition interlocks to increase seat belt use would be acceptable in their vehicles (Kidd et al., 2014).

More persistent seat belt reminders should be easier to implement. To encourage manufacturers to make improvements, IIHS began publishing seat belt reminder ratings in March 2022. Among other requirements, the audible alert must last at least 90 seconds for a vehicle to qualify for a good rating.

: 要系安全带才有AEB的话，逻辑是啥？不系安全带就是不要命所以不给开安全功能？
