1. A method comprising:
receiving, at a server computer, a first collision signature from a first client device, and a second collision signature from a second client device;
determining that a first distance between a first location of the first collision signature and a second location of the second collision signature is below a distance threshold;
increasing, based on determining that the distance is below the distance threshold, the distance threshold for a limited period of time;
receiving, at the server computer and within the limited period of time, a third collision signature from the first client device, and a fourth collision signature from the second client device;
determining that a second distance between a third location of the third collision signature and a fourth location of the fourth collision signature meets the distance threshold; and
detecting, based on determining that the second distance meets the distance threshold, a collision associated with the first and second client devices.
