The solar escape velocity from Earth's orbit (1 AU from the Sun) is 42.1 km/s. For comparison, even 1P/Halley moves at 41.5 km/s when 1 AU from the Sun, according to the formula v = 42.1219 √1/r − 0.5/a, where r is the distance from the Sun, and a is the major semi-axis. Near-Earth asteroid 2062 Aten only moves at 29 km/s when 1 AU from the Sun because of the much smaller major semi-axis.

Unlike ʻOumuamua, C/1980 E1's orbit got its high eccentricity due to a close encounter with Jupiter. Its inbound-orbit eccentricity was less than 1.
For comparison, comet C/1980 E1 will only be moving 4.2 km/s when it is 500 AU from the Sun.
The solar escape velocity from Earth's orbit (1 AU from the Sun) is 42.1 km/s. For comparison, even 1P/Halley moves at 41.5 km/s when 1 AU from the Sun, according to the formula v = 42.1219 √1/r − 0.5/a, where r is the distance from the Sun, and a is the major semi-axis. Near-Earth asteroid 2062 Aten only moves at 29 km/s when 1 AU from the Sun because of the much smaller major semi-axis.
According to CBET 4450, none of the observers had detected any sign of activity. The initial classification as a comet was based on the object's orbit.
